Abstract
The invention is a no-cable oil-immersed electric pump, comprising digitally controlled reciprocating oil-immersed electric pump and wellhead component and characterized in that: the bottom end of the wellhead component is connected with continuous high pressure nonmetallic oil pipe, the oil pipe core is equipped with metal netting, the bottom end of the oil pipe is connected through oil discharger with the top end of the digitally controlled reciprocating oil-immersed electric pump and the bottom end of the digitally controlled reciprocating oil-immersed electric pump is connected with inverter through tail pipe joint, the inverter is peripherally equipped with sleeve slide block connected with the sleeve, the top end of the metal netting of the oil pipe is equipped with lead wires connected with ground controller, the bottom end of the metal netting is connected with the input end of the inverter through the lead wires, the output end of the inverter is connected with outlet line of straight-line electric machine of the digitally controlled reciprocating oil-immersed electric pump. And it can prevent wax precipitation and blowout and reduce operation pollution. In use, the metal netting plays the role of increasing stretching resistance, weight bearing and power transmission. Because the oil pipe is continuous and has no connecting loop, as operating, it makes the remaining oil outside the oil pipe drop in the sleeve, thus assuring no-pollution operation and prolonging the service life.
Description
Technical field
The invention belongs to the deep-well oil pump in the oil recovery machiner of a kind of oil field, the cable-free oil submersible electric pump of the nonmetal high-pressure oil pipe of continous way that particularly a kind of usefulness can be reeled.
Background technique
The oil recovery machiner structure generally is made up of pumping unit, sucker rod and oil well pump both at home and abroad at present, pumping unit wherein is the power plant of oil recovery machiner, it is connected with oil pump plunger piston more than the km by sucker rod, drives pumping of plunger by its underground fluid is drawn on the ground.There are many shortcomings in existing oil recovery machiner, and is big as the volume of pumping unit, cost is high, and ineffective power consumption is big, and the main power of pumping unit is most of to be consumed in the lifting repeatedly of the above sucker rod of km, and it is very little being directly used in the power consumption of extracting fluid.Sucker rod easily leaks the pump barrel mill, and the overlength sucker rod not only increases investment, has also increased activity duration and cost, and reducing stroke influences pump efficiency.For the stripper well of later stage feed flow deficiency, pumping unit is taken out between can only implementing, and problem such as difficulty very when stopping restarting behind the well.The applicant develops a kind of " numerically controlled reciprocating submersible pump " (patent No. is ZL200420070665.1) at the problems referred to above for this reason, this oil pumping electric pump has changed original artificial lifting way and has recovered the oil, removed sucker rod, cut down the consumption of energy, improve pump efficiency, particularly solved stripper well, the horizontal well of thin poor reservoir, the oil extraction difficulty of cluster well.But the shortcoming and defect that this oil recovery mechanism also exists some to have much room for improvement: as being abutted against metal oil conduits that hoop connects as flow string on-the-spot adopt of recovering the oil more, each operation of oil well at first has been to unload metal oil conduit, metal tube about 200 is not only in occupation of very big place, what brought out lands oil also with severe contamination operation place and perimeter strip thereof, and when oil well in crude oil lifting process the wax deposition phenomenon takes place, the oil pipe passage is shut by the wax deposition alluvial, and it has the rock gas of elevated pressures down, this oil pipe is risen must cause blowout when unloading, and the crude oil that ejects will cause more large-area pollution; Electricity cable is a flat-shaped, Armor dress cable cost height, must be fixed on every branch oil pipe by anchor clamps and guard shield during assembling, go into the well with oil pipe, operation and when playing well because part anchor clamps and sheath come off, cause cable bad; In addition, the each oil well operation of oil recovery mechanism all needs operation troop, employ operating vehicle, the scene can be pursued Zhi Tisheng after holding up derrick, be dismantled, puts oil pipe, pulls down oil pipe one by one by backward after the operation, this operation numerous and diverse, consuming time tediously long, labor intensity is big, the operating cost height, difficulty is big.
Summary of the invention
The purpose of this invention is to provide a kind of cable-free oil submersible electric pump, adopt pliability preferably the nonmetal high-pressure oil pipe of continous way as flow string, reducing operation pollutes, reduce task difficulty and cost, prevent wax deposition and operation blowout, significantly improve labour productivity and reduce cost, execute-in-place is convenient, long service life.
The object of the present invention is achieved like this: it comprises numerically controlled reciprocating submersible pump and wellhead component, it is characterized in that: be connected with the nonmetal oil pipe of continuous high pressure in the wellhead component lower end, core at the nonmetal oil pipe of continuous high pressure is provided with wire netting, the lower end of this oil pipe connects the numerically controlled reciprocating submersible pump upper end by oil drainer, the lower end of numerically controlled reciprocating submersible pump connects converter plant by tail tube joint, the converter plant periphery is provided with the sleeve pipe slide block that is communicated with electrosurgical trocar, the wire netting upper end of the nonmetal oil pipe of high pressure is provided with the lead that connects ground control unit, the lower end is by the input end of lead connection converter plant, and the output terminal of converter plant connects the linear electric motor egress line of numerically controlled reciprocating submersible pump.
Advantage of the present invention is: 1, adopt the continuous high pressure oil pipe to replace to be abutted against metal oil conduit that hoop connects as flow string, can reel continuously, can directly be wound on during operation on the fixing disk, reduce the operation place.2, reduce task difficulty and operating cost significantly.3, prevent wax deposition and operation blowout, reduce operation to greatest extent and pollute.4, the wire netting of flow string had both played the increase resistance to tension in use, played load-bearing and transmission of electricity triple functions again, and nonmetal main body plays the electrical insulation effect.5, nonmetal oil pipe has excellent thermal insulation property, and inner wall smooth, makes in the crude oil lifting process cooling rate little, and crude oil is had certain insulation effect, generally speaking wax deposition not.6, because of oil pipe continuously and do not have box cupling, under the effect of well head degreasing unit, the Residual oil that oil pipe is adhered to outward falls in the sleeve pipe during operation, guarantees pollution-free operation, realizes environment protection standard.7, significantly improve labour productivity and reducing cost; 8, improve working life.
