Description

A kind of hydraulic reciprocating type rodless pumping operation pump
Technical field
The utility model relates to a kind of petroleum production device, especially a kind of oil recovery oil extraction pump.
Background technique
Low carbon emission reduction has become the 21st century worldwide problem, also will save energy and reduce the cost as the major tasks of increasing production and practising economy in domestic each oil field.Along with the further extension of petroleum exploration and development degree, the difficulty of finding self-contained high-quality reserves elephant is also strengthening gradually, and marginal reservoir reserve is in that newly to verify in the geolograph reserves proportion increasing, and hyposmosis oil well and extra-low permeability oil well are more and more.If these oil wells still adopt original oil production method, because the pumping unit volume and weight is bigger,, must be equipped with more powerful motor in order to overcome detent torque, not only increase the equipment one-time investment, also increased energy consumption greatly.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art and a kind of low power consumption, little, the lightweight a kind of hydraulic reciprocating type rodless pumping operation pump of volume is provided.This oil extraction pump does not have the ground pumping unit, does not have sucker rod, and oil pipe adopts hollow rod to substitute, and adopts the hydraulic work principle, is power with hydraulic pressure, drives reciprocating plunger pump lifting well liquid by fluid clutch, has realized low carbon emission reduction, and is energy-saving and cost-reducing.
The technological scheme that the utility model adopted is: a kind of hydraulic reciprocating type rodless pumping operation pump, form by hydraulic system, position detecting device, electric control system, reciprocating type inversion plunger pump and oil pipe.Hydraulic system is power plant, is made up of ground hydraulic station, power fluid transport tube, fluid clutch, connecting rod and connecting head, and wherein fluid clutch is connected with hydraulic station by the power fluid transport tube; Position detecting device mainly is made up of connecting valve and direction selecting controller, and connecting valve is contained in the inside of fluid clutch; One end of reciprocating type inversion plunger pump is fixedlyed connected with connecting head, and the other end is fixedlyed connected with oil pipe.The power fluid transport tube is two of process pipeline and backhaul pipelines, is connected with the two ends up and down of fluid clutch respectively.
The power fluid transport tube is the stainless steel high pressure line, is fixed in oil-pipe external wall by the stainless steel cassette tape.
Connecting rod passes connecting head and is connected with the plunger of reciprocating type inversion plunger pump, between connecting head and the connecting rod seal assembly is installed.
Oil pipe can be substituted by hollow rod.
Compared with prior art, advantage of the present utility model and beneficial effect are: this pump is applicable to hyposmosis oil well and extra-low permeability oil well, daily fluid production rate is in 0.2-3 side, thoroughly solve existing pumping unit technically and be applied in low load with strong power on the float gauging well extract, the power consumption height, the disposable apparatus investment is big, the contradiction that user cost is high.Owing to there is not pumping unit, do not need to be configured to overcome the heavy-duty motor that detent torque institute must be equipped with, dispose power of motor and have only 1-3 kilowatt, greatly reduce energy consumption; Owing to there is not sucker rod, there be not partially the rub problem of sucker rod in inclined shaft and horizontal well, this pump both can be used for peupendicular hole, also can be used for inclined shaft and horizontal well; Because adopt hollow rod to replace present oil pipe, diameter reduces greatly, the dredge oil amount of oil pipe when having saved crude oil and being lifted to waiting time on ground and operation from the down-hole; Because with hydraulic pressure is power, can very easily realize automated closed-loop control production fluid amount.
