The concentric-tube column power liquid closed-type circulating hydraulic piston pump can save the treatment expense of power liquid, is easy to ensure the quality of the power liquid, does not have the defect of inaccurate measurement of the produced liquid, and is widely applied to petroleum extraction process.
Description
One, technical field
The utility model relates to the petroleum production hydraulic piston pump, particularly a kind of concentric tube column power fluid closed-cycle hydraulic piston pump.
Two, background technique
Existing hydraulic pump is power fluid open cycle structure, and the power fluid that drives underwell pump work is the dewatered oil of separating from the production fluid of stratum.Mix draining into ground after the power fluid work again with the stratum production fluid, part crude oil is handled the back through dehydration, the degassing, desanding and is continued to use night as power.The hydraulic piston pump of this structure is that petroleum production is being brought into play and acted on, but also exists following shortcoming or deficiency simultaneously: 1. with the landing surface rise of water cut, power fluid is the treatment cost height not only, and difficult quality guarantee.2. 3. 4. because the stratum production fluid is that (power fluid after the work mixes and drains into ground, can not directly measure and sample examination it, usually causes that output miscalculation and stratum are moisture to be failed to understand etc. with lacking power fluid.
Three, summary of the invention
The purpose of this utility model provides a kind of concentric tube column power fluid closed-cycle hydraulic piston pump, adopts concentric tube to close independent runner and returns shortcoming or the deficiency that reusable structure overcomes effectively or avoids existing in the above-mentioned prior art behind the ground.
Concentric tube column power fluid closed-cycle hydraulic piston pump described in the utility model, comprise wellhead assembly, the liquor-saturated and hydraulic piston pump assembly of pipe, wellhead assembly comprises the following big four that interconnects the composition one, last big four, little four-way catcher, inner oil tube hanger, outer boll-weevil hanger and gate valve.Described tubing string is the concentric type structure, hanger is connected in the bosom, inner oil tube upper end, the lower end is connected with the Sealing plug, outer oil pipe upper end is connected with outer boll-weevil hanger, the lower end is connected in the working barrel upper end, described hydraulic piston pump assembly comprises the fishing head that is installed in the working barrel, promote leather cup, poppe tvalve core, go up expulsion valve, go up suction valve, piston, cylinder sleeve, spool, pull bar, low suction valve, the pump core that constitutes of expulsion valve, seal assembly and tailstock down, tailstock and working barrel lower end are equipped with the standing valve group.
Wherein, described pump core is the throw-in type structure.Described working barrel upper end is equipped with the seal socket sealing plug and matches with it.Described working barrel down and between the sleeve pipe annular space packet is installed.
The utility model has following advantage compared with prior art:
1, be applicable to the petroleum production of petroleum industry field, compare with power fluid open cycle hydraulic piston pump, can save the treatment cost of power fluid, the quality of easier assurance power fluid is not deposited the inaccurate defective of production fluid metering.
2, power fluid self-movement does not mix with extraction liquid, and the oilwell produced fluid amount metering is easy, and accurately measurement of water ratio is accurate.
3, the every data of oil well is clear, has improved managerial skills.
