Abstract
The utility model provides a device of suction assistance and load reduction, and relates to auxiliary equipment of drilling drill pipe of a soil layer or rock. The device of the suction assistance and the load reduction comprises a hollow shell body. The upper end and the lower end of the shell body are respectively provided with an upper connector and a lower connector. In addition, the upper portion and the lower portion of the shell body are respectively provided with an oil outlet and an oil inlet. An inner seal device is arranged in the shell body. After the device of the suction assistance and the load reduction is connected with a sucker rod in a butt joint mode, elongation deformation and bent deformation of sucker rods of different stages are both reduced, reduction rate of the elongation deformation of a first stage rod is 47.6%, the reduction rate of the elongation deformation of a second stage rod is 27.1%, and the reduction rate of the elongation deformation of the lower press-bearing portion rod is 32.4%. In addition, the auxiliary equipment of drilling drill pipe of the soil layer or the rock further plays a role of righting the sucker rod.
Description
Technical field
The utility model relates to the auxiliary equipment of creeping into drilling rod of a kind of soil layer or rock.
Background technology
Elongated in the sucker rod pumping production taken out does not have that bar is disconnected under the effect of various complex loads to be taken off phenomenon and happen occasionally, and along with the increase of pump setting depth, oil well pump efficient also descends to some extent, has had a strong impact on the normal production of oil well.Some oil fields adopt exhausting-aid device to solve the problems referred to above in succession, should not produce effect but obtain, and mainly are that exhausting-aid device is installed unreasonable and do not mated with the oil well pump model and causes.
Summary of the invention
The utility model aims to provide and a kind ofly can obviously improve helping of plunger and bottom sucker rod force-bearing situation and pump and carry a device.
Described in the utility model help to pump carry a device, comprise the housing of a hollow, housing upper, lower two ends are respectively equipped with upper and lower joint, the upper and lower part of this shell body is provided with respectively oil-out and oil-in, enclosure interior is provided with the inner sealing device.
Preferably, described inner sealing device is one way valve, and enclosure interior is provided with an inside projection at the one way valve place, and this projection and one way valve are complementary.
More preferably, described hull outside is provided with elastic sealed body.
The utility model is with after sucker rod docks, and elongation strain amount and the bending deformation quantity of each grade pumping rod all reduce to some extent, and the 1st grade of bar elongation strain amount reduction rate is 47.6%; The 2nd grade of bar elongation strain amount reduction rate is 27.1%; Bottom part in compression rod bending deflection reduction rate is 32.4%.This utility model can also play the effect of centering sucker rod in addition.
Description of drawings
Fig. 1 is the sectional view of embodiment one.
Fig. 2 is the structural representation after embodiment one installs.
The specific embodiment
As shown in Figure 1, of the present utility model helping pumps a year device, the housing 5 that comprises a hollow, housing 5 upper, lower two ends are respectively equipped with upper and lower joint 1,7, and the upper and lower part of housing 5 is provided with respectively oil-out 2 and oil-in 6, and housing 5 inside are provided with an one way valve 3, housing 5 inside are provided with an inside projection at one way valve 3 places, and this projection and one way valve 3 are complementary.In addition, described housing 5 outsides are provided with elastic sealed body 4.
During use, of the present utility model help to pump carry device and dock with sucker rod by upper and lower joint 1,7, move up and down with sucker rod, one way valve 3 is closed when up, elastic sealed body 4 under the effect of liquid weight with tubing wall formation sealing pair, help to carry oil; One way valve 3 is opened oil-feed when descending, and elastic sealed body 4 recoveries, to prevent jam.
As shown in Figure 2, described in the utility model help to pump carry a device 8 and be provided with three, after installing from lower by on be followed successively by plunger, of the present utility model helping pumps a year device, the I grade pumping rod, of the present utility model helping pumps a year device, II grade pumping rod, of the present utility model helping pumps a year device, III grade pumping rod.For make of the present utility model help to pump carry device and mate with used oil well pump specification, can also be lowered in the relevant position of each device of down-hole one section bushing pipe that is complementary with it, and bushing pipe length satisfies the stroke of device in real work.Removing of the present utility model helping and pump year device and a bushing pipe, namely is that the sucker rod combination that pumps when carrying device that helps of the present utility model is not installed.
