Fig. 2 is the syntagmatic schematic diagram of an embodiment of loess tableland rig described in the utility model.
Fig. 3 is the jackrod structure schematic diagram of loess tableland rig described in the utility model.
The specific embodiment
Theory diagram of the present utility model is seen Fig. 1, the mechanical driving device that it comprises the hydraulic control system that is made of motor, hydraulic pump, control valve, rotation motor and fuel tank, is made up of unit head and driving-chain, rig etc.Described control valve is rotation motor and lift motor two sleeving valves, and described rotation motor and lift motor output shaft drive unit head and driving-chain work respectively, realizes the drilling tool rotation and the elevating function of rig.Realize being connected by conduit under fluid pressure between described rotation motor, lift motor and control valve, hydraulic pump and operation valve, fuel tank and hydraulic pump and the control valve.
This rig also comprises interior flood pattern, and it is by water injecting pump, and the well-flushing medium transport pipeline, the injection channel in the drilling rod and the weep hole of augers that are connected between the inlet of water injecting pump and corresponding unit head are formed.Interior flood pattern is at unusual dry huge thick sand stratum, because sand adhesive power on flight is little, be not easy to be taken to the well head place by flight, so after pumping water by a small-sized water injecting pump, enter drilling rod through well-flushing medium transport pipeline, unit head, behind the arrival drill bit, discharge from the weep hole of augers, dry sand stickiness is improved, make things convenient for flight smoothly sand to be taken to the well head place.
This rig also comprises the mud origin system, it by slush pump, wash and medium transport pipeline, drilling rod in the tap of injection channel and augers form.Native system is at the excessive clay stratum of humidity, and drilling tool adopts the mud drilling drilling tool simultaneously.By the work of motor driven slush pump, output mud enters drilling rod through well-flushing medium transport pipeline, unit head, arrives the shaft bottom, and the drilling well bits are discharged to the well head place.
This rig also comprises air supply system, and it is by the injection channel in the air compressor machine that produces Compressed Gas, well-flushing medium transport pipeline, the drilling rod and adopt the drill bit of down-the-hole air hammer to form.This system drives separately Compressed Gas respectively by two cover source of the gas power plant modules, reach the down-the-hole air hammer in shaft bottom behind the interflow through well-flushing medium transport pipeline, unit head, drilling rod, drive of high-pressure gas has been impacted the work done fractured rock, and Compressed Gas can be blown out to the landwaste of shaft bottom fragmentation the well head place simultaneously.
Fig. 2 has provided one and has adopted the rig of modularized combination type structure to form schematic diagram.Among Fig. 2, the 1st, hydraulic pressure radiating module, the 2nd, rig support module, the 3rd, oil pump fuel tank module, the 4th, main frame power plant module, the 5th, hydraulic control system, the 6th, drilling tool, the 7th, unit head, the 8th, borer frame module, the 9th, oil supply system, the 10th, slush pump, the 11st, slush pump power, the 12nd, source of the gas module, the 13rd, well-flushing media feed system, the 14th, source of the gas power plant module.The rig of present embodiment is applicable to that the rig on most of huge thick loess, huge thick sand and clay stratum is the combination type drilling machine of standard configuration, and it belongs to no medium rig.Rig is by the hydraulic oil pump work of main frame power plant module 4 by belt drives oil pump fuel tank module 3, oil pump oil suction in the fuel tank, the output hydraulic oil, reversal valve through hydraulic control system drives unit head motor and lift motor work, thereby the drive unit head rotates and moves up and down, and reaches the purpose that drives drilling tool 6 instruments.Along with the rotation of spiral drill, the loess of down-hole, sand or clay take loess, sand or clay to the well head place under the effect of flight rotation lift angle, reach the drilling well purpose.
At excessive clay stratum of unusual dry huge thick sand stratum, humidity and thicker slip stone or other various lithostratigraphies, rig be equipped with foregoing in flood pattern, mud origin system and air supply system.
Among Fig. 3, provide the structural representation of a single-screw drilling rod, this rig also can adopt the double helix drilling rod.Drilling tool comprises male joint 1 among Fig. 3, flight 2, intermediate bar 3, box joint 4, shackle block key 5.Described drilling tool is the king bolt lift angle, and has water injection hole at head, makes it possess water-filling function.
The flight outer diameter D of auger stem, intermediate bar outside diameter d, lead angle β, flight helical pitch h sees shown in the figure.Because the explosive stype diameter that petroleum exploration is commonly used is two kinds of 60mm and 45mm, characteristics at the loess tableland area, the flight outer diameter D and the size range of this drilling tool: 60-100mm, the lead angle β of flight is defined as 25 °-30 °, the intermediate bar external diameter be the flight external diameter ratio i (be I=d: optimum range D) is 1: 1.4-1: 1.8, the size range of intermediate bar outside diameter d is 38-70mm.
Above parameter is determined principle: more little for media attachment power, fall as the sand layer, the i value approaches big value (1: 1.4) more, with 1: 1.4-1: 1.6 are advisable, and the β value gets the small value, and (approaching 25 °) is advisable with 25 °-28 °, media attachment power is big more, clay stratum for example, the i value approaches little value (1: 1.8), and with 1: 1.6-1: 1.8 are advisable.The β value is got big value (approaching 30 °), is advisable with 28 °-30 °.
