Abstract
The utility model relates to an oil pumping well power cylinder type hydraulic device, which consists of a hollow oil pumping rod, a pump cylinder, a plunger piston, an oil pipe, a traveling valve and a fixed valve, wherein the lower end of the hollow oil pumping rod is connected with the pump cylinder, the plunger piston is arranged in the pump cylinder, the lower end of the plunger piston is provided with the traveling valve, the hollow oil pumping rod and the pump cylinder are arranged in the oil pipe, and the lower end of the oil pipe is provided with the fixed valve. Power fluid is used as the power for a defueling pump to work in the hydraulic device, the oil pumping rod does not move, so the eccentric wear problem between the oil pumping rod and the oil pipe can be completely eliminated, which is favorable for prolonging the service life of the oil pumping rod and the oil pipe and the production cycle of the oil well, reducing the workload of workover operations, and increasing economic effectiveness.
Description
Technical field:
The utility model relates to a kind of downhole hardware that pumpingh well is produced that is used for, and belongs to the oil recovery technique class.
Background technology:
So far for a long time, sucker rod pumping is the main oil production method of domestic and international oil field widespread usage always, and the extracting device of oil equipment of conventional sucker-rod pumping well is finished oil extraction operation in the up-down stroke process repeatedly by sucker rod, oil well pump that the ground oil pumper drives in the pit shaft.A major defect of this kind oil production method is that sucker rod and oil pipe eccentric wear are affected its application life and operate as normal.In recent years, some oil fields begin to adopt closed cycle fluid power to drive oil recovery technique, for this reason, need a kind of down-hole pump that directly acts on of development to realize that closed cycle fluid power drives the hydraulic power unit that recovers the oil.
The utility model content:
The utility model purpose is to provide a kind of closed cycle fluid power of can realizing to drive the pumpingh well power cartridge type hydraulic means that recovers the oil and solve rod and tube partial-wear problem in the sucker rod pumping process.
The utility model purpose is to realize like this.This kind hydraulic means is made up of hollow rod, pump barrel, plunger, oil pipe, travelling valve and standing valve, and its structure assembled relation is as follows: the hollow rod lower end is connected with pump barrel, is provided with plunger in the pump barrel, and the plunger lower end is provided with travelling valve; Hollow rod, pump barrel place in the oil pipe, and the oil pipe lower end is provided with standing valve.During underground work, this device is placed tubing string bottom, G.I.H.Its course of work is as follows: power fluid is squeezed into the down-hole from the annular space between oil pipe and the hollow rod, and it is up to promote plunger, and it is up to drive travelling valve simultaneously, and down-hole output liquid is discharged from hollow rod; When power fluid pressure reduced to 0, plunger was descending under the effect of fluid column, and liquid is sucked space more than the travelling valve.And then carry out next stroke, so repeatedly, realizing recovers the oil continuously produces.
The utility model adopts the power of power fluid as oil well pump work, sucker rod does not move, thereby can thoroughly eliminate the eccentric wear problem between sucker rod and the oil pipe, helps prolonging the application life of sucker rod, oil pipe and the production cycle of oil well, reduce workover treatment work amount, increase economic efficiency.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.Among the figure, label " 3 " is an oil well casing.
