Operating principle and process:
One, as Fig. 2, shown in Figure 3, in the drilling fluid pressurized delivered unit I flow process:
(1) since two bench drill well pumps, two perfusion pump intakes all be connected by valve with low-pressure drilling liquid suction Trunk Line 11, the suction Trunk Line 12 of increasing the weight of to make up a prescription, therefore make the technological process of two bench drill well pumps and two charge pumps have dual circuit, low-pressure drilling liquid sucks Trunk Line 11, increasing the weight of to make up a prescription suction Trunk Line 12 can be standby each other.A certain pipeline breaks down in low-pressure drilling liquid suction Trunk Line 11, the suction Trunk Line 12 that increases the weight of to make up a prescription, and when needing repairing, available another kind of pipeline replaces.For example under the normal condition, during borehole pump 2,3 work, the suction of drilling fluid sucks Trunk Line 11 by low-pressure drilling liquid, at this moment, open respectively valve 11-2,11-3,4-2,5-2, and valve 2-1,3-1 get final product.But when valve 11-2,11-3 need change simultaneously, but valve-off 4-2,5-2 open valve 12-2,12-3,5-1,4-1 and valve 2-1,3-1, and utilizing increases the weight of to make up a prescription sucks the suction Trunk Line of Trunk Line 12 as borehole pump 2,3.
When lower or drilling fluid is thicker when drilling fluid liquid level in two drilling fluid basin 1b, the 1c, adopt the borehole pump 2,3 of plunger displacement pump possibly can't suck drilling fluid, at this moment, open charge pump 4,5 and be respectively borehole pump 2,3 intakes injection drilling fluid, because charge pump adopts centrifugal pump, its suction force is greater than borehole pump.
When occurring a large amount of drilling fluids of special circumstances needs such as leakage when the shaft bottom and injecting into well, at this moment can open 11-1,11-2,11-3,11-4 or 12-1,12-2,12-3,12-7,12-4 simultaneously, borehole pump 2,3 sucks Trunk Line 11 by low-pressure drilling liquid or the suction Trunk Line 12 that increases the weight of to make up a prescription is drawn in the drilling fluid conveying well in four drilling fluid basins simultaneously.
(2) charge pump 4,5 can be standby each other.When borehole pump 2,3 has only when work, can use any one in the charge pump 4,5 to pour into as borehole pump 2 or 3.For example, borehole pump 2 is not worked, and charge pump 4 is borehole pump 3 services, then needs valve-off 2-1,3-1, and valve-off 5-3,5-4 open 4-3,4-4,4-5, and then drilling fluid is from charge pump 4 friction jewel well pumps 3.Like this, when a charge pump fault, another alternative odd-job.
Two, as Fig. 2, shown in Figure 4, in the drilling fluid preparation unit flow process:
(1) because the pump 6 that makes up a prescription all sucks Trunk Line 11 with low-pressure drilling liquid with the intake that increases the weight of pump 7, the suction Trunk Line 12 that increases the weight of to make up a prescription is connected by valve and pipeline, therefore the technological process that make the pump 6 that makes up a prescription, increases the weight of pump 7 work has dual circuit, can not only realize making up a prescription separately processing, increase the weight of to handle, the tank switching operation, also can realize making up a prescription processing, increase the weight of to handle and carry out simultaneously, or make up a prescription that (or increasing the weight of) handles, the tank switching operation is carried out simultaneously.
A: make up a prescription separately and handle or when increasing the weight of to handle, can use increase the weight of pump 7 or the pump 6 that makes up a prescription in any one.For example, the pump 6 that makes up a prescription is used as when increasing the weight of pump, close and increase the weight of pump 7 intake valve 7-1,7-2 and outlet opening valve 7-3,7-4, open valve 12-7,12-4, open and make up a prescription pump 6 intake valve 6-1, outlet opening valve 6-3 and increase the weight of funnel suction, outlet opening valve 9-1,9-2, the pump 6 that makes up a prescription sucks drilling fluid from increase the weight of jar 1d, after increasing the weight of funnel 9 processing, return and increase the weight of among jar 1d.
B: the processing of making up a prescription, increase the weight of to handle when carrying out simultaneously, following three kinds of activitiess are arranged.
One, generally speaking, make up a prescription pump 6 with increase the weight of pump 7 and all suck Trunk Line 12 and suck from increasing the weight of to make up a prescription.At this moment, valve-off 12-7,7-2,7-4 open valve 12-4,7-1,7-3,9-1,9-2,24-4, can realize increasing the weight of handling.Meanwhile, valve-off 6-2,6-3 open 12-1,6-1,6-4,8-1,8-2,23-1, and processing simultaneously can realize making up a prescription.
Its two, make up a prescription pump 6 with increase the weight of pump 7 respectively from low-pressure drilling liquid suck Trunk Line 11, increasing the weight of to make up a prescription sucks Trunk Line 12 and sucks.At this moment, valve-off 6-1,6-3 open valve 11-1,11-7,6-2,6-4,8-1,8-2,23-1, can realize the dosing processing.Meanwhile, valve-off 12-7,7-2,7-4 open valve 12-4,7-1,7-3,9-1,9-2,24-4, can realize simultaneously increasing the weight of handling.
Its three, make up a prescription pump 6 with increase the weight of that pump 7 sucks Trunk Line 12 from increasing the weight of to make up a prescription respectively, low-pressure drilling liquid sucks Trunk Line 11 and sucks.At this moment, valve-off 6-2,6-3 open 12-1,6-1,6-4,8-1,8-2,23-1, can realize the processing of making up a prescription.Meanwhile, valve-off 7-1,7-4 open valve 11-4,7-2,7-3,9-1,9-2,24-4, can realize simultaneously increasing the weight of handling.
C: making up a prescription, (or increasing the weight of) handles, the tank switching operation is carried out simultaneously.
The tank switching operation is meant the needs according to drilling fluid conveying device technology, between several drilling fluid basins, carry out the drilling fluid allotment, when for example the liquid that increases the weight of to get well being poured into other jar, can utilize and increase the weight of pump 7 as booster pump, if this moment, do not make up a prescription, the also available pump 6 that makes up a prescription is as the booster pump tank switching.When the liquid for preparing medicine is poured into other jar, can utilize the pump 6 that makes up a prescription as booster pump, if do not increase the weight of this moment, the also available pump 7 that increases the weight of is as the booster pump tank switching.Be similar to above-mentioned b make up a prescription processing, increase the weight of to handle and carry out technological process simultaneously, make up a prescription processing, tank switching operation or increase the weight of to handle, the tank switching operation also has above-mentioned three kinds of activitiess when carrying out simultaneously, difference is, during tank switching, switching by valve, the pump that increases the weight of that plays supercharging conveying effect in the tank switching operation not only sucks from increase the weight of jar, and may suck from arbitrary drilling fluid basin, and returning can be to other arbitrary drilling fluid basin when discharging.At this moment the course of work that (or increasing the weight of) handles, the tank switching operation is carried out simultaneously is not described in detail about making up a prescription.
(2) since make up a prescription pump 6 and the outlet opening that increases the weight of pump 7 increase the weight of to make up a prescription and discharge Trunk Lines 14,13 and be connected with two respectively by valve and pipeline respectively, thereby make make up a prescription pump 6 with increase the weight of pump 7 can be standby each other.When increasing the weight of processing separately or make up a prescription processing, can use and make up a prescription pump 6 and increase the weight of arbitrary work in the pump 7.For example, break down when increasing the weight of pump 7, when system needs to increase the weight of to handle again, close and increase the weight of pump suction and each valve of outlet opening, valve-off 6-2,6-4, open valve 12-4,12-7,6-1,6-3,9-1,9-2,24-4, the pump 6 that makes up a prescription is worked, and can send back to after increasing the weight of to handle and increase the weight of in jar 1d from increasing the weight of to suck drilling fluid in jar 1d.
(3) under the special process environment, when a bench drill well pump uses, discharge as borehole pump 2 normal suctions, the pump 6 that makes up a prescription, increase the weight of charge pump 5 on pump 7 and another slush pump 3 and can participate in simultaneously making up a prescription or increase the weight of and handle.When participating in increasing the weight of to handle as charge pump 5, need valve-off 5-2,3-1, open valve 12-4,12-7,5-1,5-3,5-4,3-2,9-1,9-2,24-4, charge pump 5 work, can be from increasing the weight of to suck drilling fluid in jar 1d, oppositely being pressed into increases the weight of to make up a prescription discharges Trunk Line 14, increases the weight of in jar 1d by increasing the weight of to send back to after funnel 9 increases the weight of to handle.
Three, as Fig. 2, shown in Figure 5, in the drilling fluid pressurized delivered unit II flow process:
Be the well cementation pump, drilling fluid gun, the supply jar, blowdown tank is carried the export pipeline 17 of drilling fluid, 16,18,19 all by Trunk Line 15, valve 13-1,14-1 discharges Trunk Line 14 with increasing the weight of to make up a prescription respectively, 13 connect, utilization increase the weight of pump 7 or the pump 6 that makes up a prescription as booster pump, discharge Trunk Line 14 by increasing the weight of to make up a prescription, arbitrary pipeline in 13, can realize to the well cementation pump, drilling fluid gun, the supply jar, drilling well supporting facility such as blowdown tank are carried drilling fluid, use the dual circuit design of drilling fluid preparation unit, realized the dual circuit design of each feed-line, utilize simultaneously and increase the weight of pump and the pump standby functions each other of making up a prescription, guarantee each export pipeline operate as normal, caused the problem that stops operation when having solved pipeline or equipment fault to the full extent.Can be participated in increasing the weight of handling as can be known by aforementioned charge pump, charge pump has to substitute and increases the weight of pump or the function of the pump work that makes up a prescription, and can be used as their stand by pump.Therefore during special requirement, two charge pumps also can be used as booster pump and carry drilling fluids for drilling well supporting facility such as well cementation pump, drilling fluid gun, supply jar, blowdown tanks.
To carry drilling fluid to drilling fluid gun is example, and the course of work of drilling fluid pressurized delivered unit II is described.Be installed on drilling fluid gun 10-1,10-2,10-3,10-4,10-5 in drilling fluid basin 1a, 1b, 1c, the 1d, after receiving the drilling fluid of supercharging, can wash away and make it the deposit that is deposited on drilling fluid basin 1a, 1b, 1c, 1d bottom and fully mix with drilling fluid, in the time of clear jar, wash away the pot bottom sand setting, be deposited in the drilling fluid basin to prevent landwaste.When drilling fluid gun is carried drilling fluid, increase the weight of pump 7 or the pump 6 that makes up a prescription in any work, open 13-1 or 14-1, open valve 16-1 and get final product.In like manner, when needs when well cementation pump, supply jar are carried drilling fluid, increase the weight of pump 7, any work in the pump 6 that makes up a prescription, open valve 13-1 or 14-1, open valve 17-1,18-1 and get final product.When drilling fluid basin 1a, 1b, 1c, 1d need indivedual or whole blowdowns to clean, increase the weight of pump 7 or the pump 6 that makes up a prescription in any work, open valve 13-1 or 14-1, open valve 19-1, most of sewage is transported to blowdown tank fast in the drilling fluid basin, and jar remaining drilling fluid in the end can be released to blowdown tank by opening the valve 12-8 that sucks Trunk Line 12 ends that increases the weight of to make up a prescription.If charge pump 4 substitutes and increases the weight of pump 7 or the pump 6 that makes up a prescription is carried drilling fluid as booster pump for the supply jar, at this moment close 2-1,4-5, open 4-3,4-4,2-2,13-1,18-1 gets final product.
Four,, increase the weight of pump 7 or make up a prescription the stand by pump of pump 6 as charge pump as Fig. 2, shown in Figure 6.Charge pump 4,5 also can be used as the stand by pump that increases the weight of pump 7 or make up a prescription pump 6 conversely.To increase the weight of pump 7 or the pump 6 that makes up a prescription is an example as the stand by pump of charge pump, when in the charge pump 4,5 one or two when damaging simultaneously, can use increase the weight of pump 7 or the pump 6 that makes up a prescription individually or simultaneously as charge pump, open valve 2-2 and can replace charge pump 4, open valve 3-2 and can replace charge pump 5.Use the dual circuit design of drilling fluid preparation unit, increase the weight of pump 7 or the pump 6 that makes up a prescription has also been realized the dual circuit design when using as charge pump, utilize simultaneously and increase the weight of pump and the pump standby functions each other of making up a prescription, can make and increase the weight of pump 7 or the pump 6 that makes up a prescription can be used as arbitrary charge pump, cause the problem that stops operation when having solved pipeline or equipment fault to the full extent.During work, if increase the weight of pump 7 as charge pump be borehole pump 2 for drilling fluids, increase the weight of pump 7 and suck Trunk Line 11 from low-pressure drilling liquid and suck, then need valve-off 7-1,7-3, open 11-2 or 11-3, open valve 11-7,7-2,7-4,2-2 get final product.If make up a prescription pump 6 as charge pump is borehole pump 3 for drilling fluids, and the pump 6 that makes up a prescription sucks Trunk Line 12 from increasing the weight of to make up a prescription and sucks, and then needs valve-off 6-2,6-4, opens valve 12-2 or 12-3, open valve 6-1,6-3,3-2 gets final product.Other situation is not enumerated one by one.Charge pump 4,5 conducts increase the weight of pump 7 or the stand by pump of the pump 6 that makes up a prescription explains in front.
Five, in the aforementioned processing of making up a prescription, increase the weight of to handle on the basis of three kinds of activitiess of carrying out simultaneously, realize borehole pump conveying, the processing of making up a prescription, to increase the weight of to handle the activities of carrying out simultaneously as follows:
One, as shown in Figure 2, generally speaking, make up a prescription pump 6 with increase the weight of pump 7 and all suck Trunk Line 12 and suck from increasing the weight of to make up a prescription.At this moment, at this moment, borehole pump 2,3 can only suck Trunk Line 11 from low-pressure drilling liquid and suck, and sucks if suck Trunk Line 12 from increasing the weight of to make up a prescription, and then with the suction line condominium line that makes up a prescription, causes the pipeline confusion.During borehole pump 2,3 work, open valve 11-2,11-3 simultaneously or only open valve 11-2, or only open valve 11-3, valve-off 12-2,12-3, valve-off 4-1,5-1, open valve 4-2,5-2,2-1,3-1, borehole pump 2,3 respectively by low-pressure drilling liquid suck Trunk Line 11 in drilling fluid basin 1b, the 1c simultaneously or only from drilling fluid basin 1b or only suck drilling fluid work from drilling fluid basin 1c.
Its two, make up a prescription pump 6 with increase the weight of pump 7 respectively from low-pressure drilling liquid suck Trunk Line 11, increasing the weight of to make up a prescription sucks Trunk Line 12 and sucks.At this moment, need open valve 11-7, valve-off 12-7, borehole pump 2,3 must suck Trunk Line 12 from increasing the weight of to make up a prescription and suck, and sucks and can not suck Trunk Line 11 from low-pressure drilling liquid.If from then low-pressure drilling liquid suction Trunk Line 11 suctions, the suction line condominium line that then causes and make up a prescription causes the pipeline confusion.During borehole pump 2,3 work, open valve 12-2,12-3 simultaneously, or only open 12-2 or only open 12-3, valve-off 11-2,11-3, valve-off 4-2,5-2, open valve 4-1,5-1,2-1,3-1, borehole pump 2,3 suck by increasing the weight of to make up a prescription respectively Trunk Line 12 in drilling fluid basin 1b, the 1c simultaneously or only from drilling fluid basin 1b or only suck drilling fluid work from drilling fluid basin 1c.
Its three, make up a prescription pump 6 with increase the weight of that pump 7 sucks Trunk Line 12 from increasing the weight of to make up a prescription respectively, low-pressure drilling liquid sucks Trunk Line 11 and sucks.At this moment, need valve-off 11-7, valve 12-7, borehole pump 2,3 can only suck Trunk Line 11 from low-pressure drilling liquid and suck, and sucks and can not suck Trunk Line 12 from increasing the weight of to make up a prescription.Suck if suck Trunk Line 12 from then increasing the weight of to make up a prescription, the suction line condominium line that then causes and make up a prescription causes the pipeline confusion.During borehole pump 2,3 work, open valve 11-2,11-3 simultaneously, or only open 11-2 or only open 11-3, valve-off 12-2,12-3, during borehole pump 2,3 work, valve-off 4-1,5-1 open valve 4-2,5-2,2-1,3-1, borehole pump 2,3 respectively by low-pressure drilling liquid suck Trunk Line 11 in drilling fluid basin 1b, the 1c simultaneously or only from drilling fluid basin 1b or only suck drilling fluid work from drilling fluid basin 1c.
Six, handle aforementioned making up a prescription (or increasing the weight of), on the basis of three kinds of activitiess when the tank switching operation is carried out simultaneously, can realize that borehole pump conveying, the processing of making up a prescription, tank switching operation carry out simultaneously, here enumeration no longer.
By as seen above-mentioned, the utility model is because the design of utilization dual circuit, switch by valve, can not only realize carrying out separately borehole pump carries, increases the weight of to handle, makes up a prescription and handle or the tank switching operation, can also realize borehole pump conveying, the processing of making up a prescription, increase the weight of to handle and carry out simultaneously, or borehole pump is carried, made up a prescription, and (or increasing the weight of) handles, tank switching is handled and carried out simultaneously, the pump 6 that perhaps makes up a prescription, increases the weight of pump 7 and a charge pump participates in preparing fast drilling fluid simultaneously.Simultaneously, standby functions and dual circuit design have spare duct because the equipment of identical category has each other by circuit design, have solved in the prior art because maintenance of equipment and replacing, pipeline maintainance cause the problem that stops operation.
