Abstract
The speed governing type centralized defeated new process in airtight oil station is a kind of new oil-gas gathering and transferring technology.Belong to oilfield gathering and transportation technology class.Its production tooling is made of airtight disconnector, Level meter, controller, stepless speed-regulating device and pump group.Its purposes is to realize the airtight and automatic guidance of oil station oil-gas gathering and transportation.Its principle of work is that liquid level with airtight disconnector is as the control signal source, handle direct change the in back after testing and drive revolution speed, change pump capacity, to reach in unit time, the dynamical equilibrium that enters liquid measure and output liquid amount of airtight disconnector realizes that oil-gas closed collection is defeated.
Description
The present invention's a kind of oil station oil-gas gathering and transportation new process of touching upon.
The invention belongs to oilfield gathering and transportation technology class.
At present, the oil-gas closed gathering and transportation technology of valve regulated formula of Oilfield using, it is many to exist power consumption, the production process instability, the disadvantage that failure frequency is high can not satisfy the defeated needs of oil-gas closed collection.
Order of the present invention ground is that oil-gas closed collection is defeated to provide a kind of new technology for oil is stood, and to reach economize on electricity, consumption reduction and safe and reliable oil-gas closed collection are failed.
Accompanying drawing 1 is a process flow diagram of the present invention.All production tooling is by airtight separation container 1, and Level meter 2, controller 3, stepless speed-regulating device 4 and oil transportation pump group 5 are formed.
As shown in Figure 1, after the oil gas water mixed liquid enters airtight separation container 1 by the C mouth, gas phase and liquid phase separation in 1.Gas phase A is on top, and liquid phase B is in the bottom, and its dividing range is gone up shown in the palpus line for figure.Under (hereinafter to be referred as liquid level, promptly dividing range is apart from the container bottom height) ordinary production state, should be that liquid level remains in the scope of specified value.Direct-operated regulator D has kept the force value of stipulating in the airtight disconnector.Gas also enters the gas net through this valve.Liquid enters fuel transfer pump 5 by discharge pipe E, and is pumped to flow circuit.Desire to make liquid level to remain in the specialized range, airtight separator flask in unit time inlet and output are equated, promptly the inlet in the unit time equals discharge of pump.The inlet of unit time is the variable of not controlling, therefore discharge of pump also just must be the variable that changes synchronously with the inlet standard under slave mode, can reach the requirement that liquid level remains at the specified value scope, the controlled way that forms the ordinary production state pump capacity of closed process have two kinds a kind of be to regulate the control pump outlet valve aperture that closed gathering technology adopted at present to change pepeline characteristic, control the mode of capacity of pump indirectly.Another kind of then be that the present invention adopts the rotating speed that changes pump, the mode of direct control capacity of pump.
The present invention is with the liquid level of the airtight disconnector signal source as the control pump discharge capacity.When airtight separation container 1 enters liquid measure when increasing by import C, liquid level is tending towards raising, this appreciation is measured by Level meter 2, become electric signal and reach controller 3, electric signal reaches stepless speed-regulating device 4 after conversion is amplified, improve by 4 and drive revolution speed, has increased the discharge capacity of pump 5 accordingly, make the output and the inlet of airtight separation container 1 reach new balance, liquid level then remains within the specified value scope.Otherwise, airtight disconnector 1 enter liquid measure when reducing, the liquid level trend descends, this depreciation, still reach stepless speed-regulating device 4 again through above-mentioned detector 2 and controller 3, device 4 has reduced and has driven revolution speed, has reduced the discharge capacity of pump 5 accordingly, make the output and the input of airtight disconnector 1 reach new balance again, liquid level is remained within the specified value scope.In this dynamic changing process, the output of airtight disconnector and the variation of input are accurate to carry out synchronously, so the changing value of liquid level can remain within the specialized range all the time, have satisfied the defeated arts demand of oil-gas closed collection.
Compare with the oil-gas closed gathering and transportation technology of valve regulated formula of present employing, the invention has the advantages that: (1) economize on electricity makes to regulate the discharge capacity throttle loss that is caused because of having saved the pump discharge valve.(2) liquid level signal direct control pump capacity after treatment is highly sensitive, satisfies the defeated needs of oil-gas closed collection.(3) control system does not have the mechanical breakdown point, and is safe and reliable.
Realization of the present invention can utilize existing airtight disconnector, selects the Level meter of different model for use, controller, and frequency converter or stepless speed adjusting gear and pump group can be formed.
Claims (2)
1, the present invention is a kind of novel speed governing type oil-gas gathering and transferring technology.Its production tooling is to be combined by airtight separation container 1, Level meter 2, controller 3, stepless speed-regulating device 4 and fuel transfer pump group 5.
2, the principle of the oil-gas closed gathering and transportation technology of speed governing type is: the liquid level pressure differential pressure that utilizes leakproof tank is as the control signal source, records signal and controls stepless speed-regulating device after treatment and directly change and drive revolution speed and pump capacity.
