Description
Technical field
The utility model relates to field of petroleum exploitation, is a kind of oil pumper specifically.
Background technology
Oil pumper is a kind of machinery equipment of recover petroleum, is commonly called as " machine of kowtowing ", makes oil go out well by the way of pressurization.When oil pumper upstroke, oil pipe elastic shrinkage moves upward, and driving mechanical block-relief oil production device moves upward, and clashes into sliding sleeve and produces vibration; Meanwhile, copper current only valve cuts out, and reducing piston assembly shutoff oil is when oil pumper down stroke, and oil pipe elastic elongation moves downward, and driving mechanical block-relief oil production device moves downward, and clashes into sliding sleeve and produces vibration; Meanwhile, reversed check valve part is closed, and reducing piston assembly is shutoff oil jacket ring shaped oil passage still, makes reversed check valve lower zone form higher-pressure region, and the oil flow channel of this motion again in formation produces a kind of reverse impact force.
Oil pumper contains crude oil and a small amount of natural gas from oil well produced Produced Liquid.Outer defeated time need crude oil and natural gas to separate.Existing oil gas separation is poor, and part crude oil can enter escape pipe with natural gas, is unfavorable for the outer transporting operation after being separated.
In Chinese Patent Application No.: disclose a kind of pumping unit of well mouth in 201410632450.2, comprise sucker rod, also comprise switched reluctance machines, reducer, rotating disk, eccentric shaft and motor control box; Described switched reluctance machines one end is electrically connected with motor control box, and the other end is connected by universal driving shaft with rotating disk, and described rotating disk is provided with eccentric shaft, and described sucker rod is connected with eccentric shaft.This technical scheme oil gas can not be separated in time, can not remove the impurity in crude oil.
In view of above-mentioned defect, the utility model creator obtains this creation finally through long research and practice.
Summary of the invention
For the problems referred to above, the utility model provides a kind of oil pumper, is convenient to removal of impurities, Oil-gas Separation.
In order to solve the problem, the technical scheme that the utility model provides is:
A kind of oil pumper, comprise oil pumper body, comprise gas and oil separating plant, oil inlet pipe, flowline, described flowline is communicated with described oil pumper body, gas and oil separating plant; Described oil inlet pipe is provided with removal of impurities pipe, is provided with screen pack in this removal of impurities pipe, the axis oblique of this screen pack and described oil inlet pipe, and the top of this screen pack withstands on the inner side of the tube wall of described oil inlet pipe, and described removal of impurities pipe is provided with valve.
Utilize the impurity in filter screen filtration crude oil, when the impurity on screen pack is too much, open valve, utilize crude oil to be washed away by impurity, dedoping step is simple, quick.
Preferably, oil pumper also comprises motor, described gas and oil separating plant comprises shell body, inner housing, and described shell body is provided with gas outlet, and described inner housing is provided with some oil-outs, described shell body is communicated with described flowline, described inner housing is communicated with described oil inlet pipe, and the bottom of described inner housing is provided with extension, and this extension stretches out through described shell body, this extension is provided with the first gear, and the output shaft of described motor is provided with the second gear be meshed with described first gear.
Crude oil enters in inner housing by oil inlet pipe, and motor is rotated by the first gear, the second gear driven inner housing, under the influence of centrifugal force, crude oil gets rid of on the sidewall of shell body through oil-out, can not enter gas outlet, complete Oil-gas Separation with natural gas, good oil gas separation effect, efficiency is high.
Preferably, be provided with baffle plate between the sidewall of described inner housing and described shell body, this baffle plate is provided with some air-vents, and described gas outlet is placed in the top of described baffle plate.Prevent crude oil from entering in gas outlet further.
Preferably, the end of described removal of impurities pipe is provided with capping.Prevent leakage of oil.
Compared with prior art, the beneficial effects of the utility model are:
Oil pumper of the present utility model effectively can remove the impurity in crude oil, and can allow Oil-gas Separation, one end degree extends the application life of oil pumper, uses convenient.
