Abstract
The utility model relates to an apparatus for underground exploitation of crude petroleum oil. At present, a bar type oil pumping unit is mainly used in petroleum oil exploitation. The utility model adopts a hydraulic pump to plunge into a jacket pipe of a petroleum oil well and to expel the crude oil to the ground, and a hydraulic power controller is arranged on the ground. The utility model has the advantages of controllable and adjustable properties, lower cost compared with the bar type oil pumping unit, high efficiency, large yield, easy maintenance and few accidents.
Description
The utility model is a kind of device exploitation that is used for oil extraction under the oil well.
At present, the universal method that each oil-producing country of the world recovers the oil is to use rod beam-pumping unit, this equipment is with a long pull bar of going up km, back and forth spurs the piston rod of oil cylinder in the oil well, and piston rod drives piston, the pump drainage oil, oil is pumped to ground through the pipeline of oil well.According to drawing U.S.'s sieve Scirocco in " elevate a turnable ladder method oil production technology " book of U.S. KE cloth youth chief editor 518867 mouthfuls of oil-producing wells are investigated and analysed, adopted the well of rod beam-pumping unit to account for 85.2%; Chlorine is lifted and is accounted for 10.8%; ESP accounts for 2%; The hydraulic piston pump sump accounts for 2%, has 383000 mouthfuls of artificially lifted wells (referring to nonartesian well) to be stripper well (being lower than 10 barrel per days).Rod beam-pumping unit not only yields poorly, and mechanical efficiency is also low, is generally about 50%.The dark more efficient of well is low more, and operating reliability is poor.According to investigations:, frequent gug maintenance, every month real work number of days of every mouthful of well less than 20 days, about 100,000 yuan/month of recondition expense for guaranteeing that major accident does not appear in rod beam-pumping unit.
The external electric submersible pump of development in recent years though efficient is higher, involves great expense.
Through the Searches of Patent Literature, do not find the patent close with the utility model.
The purpose of the utility model development is: improve oil recovery efficiency, reduce cost for oil production, reduce amount of maintenance, improve the individual well oil production rate, use manpower and material resources sparingly.
The utility model structure adopts the pump housing of tubulose, the main drive cylinder 6 that drives with hydraulic oil is installed in the middle of two plunger pumps, piston 5 is arranged in the drive cylinder, piston 5 is by the liquid that advances back of drive cylinder both sides, transmission by axle, piston 7 about driving in two the isopyknic plungers in both sides and 8 motions, respectively there are a feed liquor valve 9 and 10 in the termination of two plunger pumps, and a liquid valve 11 and 12 are respectively arranged.Sealing mutually between drive cylinder and the crude oil plunger pump.Hydraulic power station 1 is arranged at ground, and hydraulic power station separates with the pump housing, and hydraulic oil is connected in hydrovalve 4 on the pump housing by pipeline 2 and 3, and through the distribution of hydrovalve 4, hydraulic oil flow moves piston 5 and moves to drive cylinder 6 districts.The pump housing is suspended in the oil well casing by wire rope 14, and oil pipe line between the hydraulic station and the pump housing and crude oil oil exit pipe 13 adopt flexible conduit, and wire rope and oil pipe in the oil well cover connect with clamp.
Adopting the hydraulic pressure immersion pump to compare with used rod beam-pumping unit has the following advantages:
1, the pump that slips in the oil well petroleum casing pipe is passive pump, and its discharge capacity and pressure are by control of ground hydraulic power station and adjusting, comparatively convenient.
2, mechanical efficiency is higher, and efficient of the present utility model can reach more than 80%.
3, output is higher, under equal natural condition, estimates that comparable rod beam-pumping unit exceeds 30～50%.
4, operating reliability is strong, and the utility model machining accuracy is higher, good seal performance.Higher wear resistance is arranged and than the long-life, accident rate is low, the repair cycle is long.
5, adaptability is good, and the utility model not only is fit to the oil field, land, also can adapt at offshore oil field.
6, low equipment investment, the comparable rod beam-pumping unit of the utility model is saved 40～50% investment, than the investment of electric submersible pump saving 60～70%, and also little in the ground floor space, concrete foundation is also less relatively.
Accompanying drawing is that the utility model is arranged on the cross-sectional schematic in the oil well casing.
It is as follows to implement mode of the present utility model: the pump housing is after ground manufacturing assembling finishes, putting into oil well casing by wire rope 14 liftings goes into the well, hydraulic pipe line 2 and 3 and crude oil oil exit pipe 13 connect with the pump housing and also put into the down-hole gradually with wire rope, and every one clamp of tens meters cards, the pump housing is put into former oil reservoir and is promptly stopped, hydraulic tube 2 and 3 and crude oil oil exit pipe 13 is connected to respectively on hydraulic power station 1 and the crude oil pipeline then.
After the ground hydraulic power station starts, piston 5 in the pump in the drive cylinder 6 is with the turnover of hydraulic oil different direction, and the piston 7 and 8 of drive plunger pump, when piston 7 and 8 motions in feed liquor valve 9 and 10, under liquid valve 11 and 12 the control crude oil is drained in the crude oil oil exit pipe 13, be depressed into ground.
Claims (4)
1, the deep diving oil well pump that surges, it is characterized in that: the hydraulic driving power station separates with the pump housing, the pump housing is a tubulose, include: driving oil cylinder and piston, reach two isopyknic plunger cases and piston, selector valve is installed on the pump housing, and in oil well casing, the crude oil oil exit pipe adopts flexible conduit to its pump housing by wire rope suspensioning.
2, according to claim 1, the deep diving oil well pump that surges is characterized in that: the two ends of oil well pump are separately installed with liquid sucting valve and draining valve.
