Abstract
The utility model relates to a sand stopping device on an oil well pump, which is composed of an oil conduit on an oil well pump, a centralizing joint, a sucker rod, a pressing sleeve, a mobile sleeve, a semi-circle block A, a semi-circle block B, a fixing sleeve, a stop sleeve and an upper joint of the oil well pump, wherein the lower part of the oil conduit on the oil well pump is connected with the upper joint of the oil well pump, the stop sleeve is positioned in the connecting position of the lower part of the oil conduit on the pump and the upper joint of the oil well pump, the fixing sleeve is pressed and fixed on the stop sleeve, the mobile sleeve is positioned on the fixing sleeve, the semi-circle block A and the semi-circle block B are positioned in the mobile sleeve, the semi-circle block A and the semi-circle block B are combined as a hollow cylinder, the sucker rod passes through the semi-circle block A and the semi-circle block B, the upper part of the sucker rod is connected with the centralizing joint and the pressing sleeve is connected with the upper part of the mobile sleeve. The utility model has the function of stopping sand, the utility model solves the problem that the oil well is stuck by the sand when the oil well pump comes out of a sand well and stops pumping, the wear of the oil well pump is relieved, when the oil well pump is lowered into the well, a tubing string does not need to be matched with other tools, no connecting position is added, no accident potential exists and the cost is low.
Description
One, technical field
The utility model is a sand device on the oil well pump pump in a kind of oil field pumping well, belongs to engineering goods.
Two, background technique
The common oil well pump sand control card ability of oil field use at present is relatively poor, in sand well uses, when causing the pumping unit stop pumping, be sunken under the sand grains on the oil well pump in the oil pipe on the piston of oil well pump, often cause piston, the pump barrel of sand card oil well pump and sand grains wearing and tearing oil well pump because of reasons such as power failures.In case sand card accident takes place, will carry out maintenance operation, both influenced crude output, increase operating cost again.Behind the piston of sand grains wearing and tearing oil well pump, the pump barrel, pumping well is short duty cycle, the workover cost height, and economic benefit is low.
Three, summary of the invention
The purpose of this utility model is a sand device on a kind of oil well pump pump of design, and sand device is installed on the oil well pump on this oil well pump pump, plays the effect of sand block sand control, to guarantee the oil well pump proper functioning, reduce or avoid sand card oil well pump, prolong the workover rig service to oil well cycle, increase economic efficiency.
The purpose of this utility model be achieved in that it by oil pipe on the pump, set upright joint, sucker rod, gland, move cover, semicircle piece A, semicircle piece B, fixed cover, interstage sleeve, oil well pump upper connection form.The oil pipe bottom connects with the oil well pump upper connection on the pump, interstage sleeve is placed in oil pipe bottom and oil well pump upper connection connection place on the pump, the internal diameter of interstage sleeve can be by the piston of oil well pump, the fixed cover wedge is on interstage sleeve, movable sheath seat drops on the fixed cover, semicircle piece A, semicircle piece B is placed in and moves in the cover, semicircle piece A, semicircle piece B synthesizes a hollow cylinder, sucker rod passes semicircle piece A, semicircle piece B, the sucker rod bottom connects with the oil well pump piston, sucker rod top with set upright joint and connect, gland with move cover top and connect, fixing semicircle piece A, the effect of semicircle piece B.
During installation, earlier interstage sleeve is put in the oil well pump upper connection, because oil well pump upper connection screw thread is a tapered thread, so interstage sleeve can not fall in the pump, then oil pipe on the pump is connected with the oil well pump upper connection, thereby interstage sleeve is fixed on oil pipe bottom and oil well pump upper connection connection place on the pump, and with oil pipe elder generation G.I.H on oil well pump and the pump.Then the sucker rod bottom is connected with the piston of oil well pump, again fixed cover, mobile cover are inserted on the sucker rod body of rod from the rod connector end, rod connector is a jumping-up, diameter is greater than the body of rod, the internal diameter of fixed cover, mobile cover can be inserted in from it, and then semicircle piece A, semicircle piece B put into move cover, gland is connected with mobile cover top, set upright joint and connect, make and set upright joint, sucker rod, gland, move cover, semicircle piece A, semicircle piece B, fixed cover becomes one and together be lowered on the pump in the oil pipe with piston, the sucker rod of oil well pump with sucker rod top.
Because interstage sleeve upper end-hole inlet angle is identical with fixed cover bottom cone angle and less than angle of friction, after so piston is lowered in the oil well pump, under pressure, fixed cover is fixed on the interstage sleeve, during descending the or stop motion of sucker rod, gland, mobile cover, semicircle piece A, semicircle piece B are landed on the fixed cover motionless, work to block sand, and sand can not fall into piston, the pump barrel of interior holddown of pump and wearing and tearing oil well pump; When sucker rod is up, gland, move cover, semicircle piece A, semicircle piece B leaves fixed cover under the effect of liquid stream up, liquid stream is passed through, thereby under the situation that does not influence production, plays the effect of sand block.
The beneficial effects of the utility model are: sand device has the sand block effect on this oil well pump pump, the problem of sand card oil well pump when having solved the sand output well stop pumping, piston, the pump barrel wearing and tearing of oil well pump when producing have been slowed down, this tools structure is simple, easy for installation, because of oil pipe, sucker rod, oil well pump upper connection on the stressed member pump are on-the-spot preparation, so, not be used in supporting other instrument on the tubing string when going into the well, do not increase connection part, there is not accident potential, and low cost of manufacture, remarkable economic efficiency therefore had.
Four, description of drawings
Accompanying drawing is a structure installation diagram of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Among the figure: the 1st, oil pipe on the pump, the 2nd, set upright joint, the 3rd, sucker rod, the 4th, gland, the 5th, move cover, the 6th, semicircle piece A, the 7th, semicircle piece B, the 8th, fixed cover, the 9th, interstage sleeve, the 10th, the oil well pump upper connection, promptly the utility model by oil pipe on the pump 1, set upright joint 2, sucker rod 3, gland 4, move cover 5, semicircle piece A6, semicircle piece B 7, fixed cover 8, interstage sleeve 9, oil well pump upper connection 10 form.Oil pipe 1, sucker rod 3, oil well pump upper connection 10 are on-the-spot existing part on the pump.Oil pipe 1 bottom connects with oil well pump upper connection 10 on the pump, interstage sleeve 9 is placed in the connection place of oil pipe 1 bottom and oil well pump upper connection 10 on the pump, the internal diameter of interstage sleeve 9 can be by the piston of oil well pump, fixed cover 8 wedges are on interstage sleeve 9, moving cover 5 is located on the fixed cover 8, semicircle piece A6, semicircle piece B 7 is placed in and moves in the cover 5, semicircle piece A6, semicircle piece B7 synthesizes a hollow cylinder, sucker rod 3 passes semicircle piece A6, semicircle piece B 7, sucker rod 3 bottoms connect with the oil well pump piston, sucker rod 3 tops with set upright joint 2 and connect, gland 4 with move cover 5 tops and connect, fixing semicircle piece A6, the effect of semicircle piece B7.
