Description
Technical field
The two-way logical oil well pump that the utility model provides a kind of petroleum industry viscous crude and thin oil oil well production to use.
Background technique
At present, heavy crude well steam injection technology mostly adopts traditional mode on the oil field: be lowered to steam injection string-steam injection-vexed well-open flow-kill-job-trip out steam injection string-be lowered to manufacturing process that flow string-Kai takes out production, complex procedures, it is long that not only investment height, and operation accounts for the well time; The thin oil oil well production string is because structural defective, can't carry out direct flushing, the sand washing of inspection pump could play oil pipe to carry out the sand washing operation after also former well casing post all can only being proposed, if it is tight to run into the oil well pipe screw thread, be difficult to shackle, cementing truck then often appears, the tank car scene problem of awaiting orders for a long time, cause sand washing to fail in one's scheme, in addition, crude oil scatters ground and causes ground ring mirror to pollute in the above oil pipe of oil well pump when preventing operation, is convenient to the well head workman and operates construction, also frequent supporting installation oil drainer on the tubing string, oil drainer can smooth opening under the normal condition, but occurs that pump rod is disconnected to take off phenomenon, and oil drainer also just can't be opened.
Summary of the invention
The purpose of this utility model is: provide a kind of petroleum industry viscous crude and thin oil oil well production with two-way logical oil well pump.
The utility model is achieved in that and comprises upper connection, outer pump barrel, interior pump barrel, two-wayly leads to through hole, upper travelling valve, equal diameter long-term job plug, lower travelling valve, standing valve, lower contact, upper connection is connected with outer pump barrel, lower contact is connected with outer pump barrel, outer pump barrel is connected with interior pump barrel, equal diameter long-term job plug is housed in the interior pump barrel, the bottom of interior pump barrel is connected with standing valve, is respectively arranged with upper travelling valve, lower travelling valve in the equal diameter long-term job plug.
Have the two-way through hole that leads on the interior pump barrel.
Two-way entire length of leading to the distance 〉=equal diameter long-term job plug between through hole and the standing valve.
The length of outer pump barrel is greater than the length of interior pump barrel.
Advantage of the present utility model is: 1. after adopting two-way logical oil well pump, need only and carry over-stroke, piston is closed the two-way through hole that leads to, and just can directly open and take out production; As long as transfer piston at the bottom of the pump, just can open the two-way through hole that leads to, carry out steam injection, positive well-flushing or positive sand washing operation; Any oil drainer need be installed on the completion tubular column, during workover eration in the above oil pipe of oil well pump crude oil can leak into smoothly in the well, avoid oil drainer can't open crude oil and scatter ground and cause ground ring mirror pollution problem; 2. two-way logical oil well pump overall structure is simply compact, and sealing is reliable, stable performance, and its length can be regulated according to on-the-spot needs, and manufacturing, installation, dismounting and replacing are convenient.
Can realize steam injection and oil pumping production integration tubing string for thick oil well, that is: be lowered to steam injection and take out the manufacturing process of production with oil pumping production integration tubing string-steam injection-vexed well-open flow-Kai; For the thin oil oil well, the one, well-flushing just, can not trip out former well casing post, only need to deepen tubing string and can realize positive sand washing, be convenient to arrange the sand washing plan, reduce investment outlay, shorten operation and account for the well time, the 2nd, can realize oil drainer is not installed on the tubing string, even the disconnected phenomenon of taking off of pump rod occurs, tubing string still can draining during operation, avoids causing ground ring mirror pollution problem.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, the utility model comprises upper connection 1, outer pump barrel 2, interior pump barrel 3, two-way through hole 4, upper travelling valve 5, equal diameter long-term job plug 6, lower travelling valve 7, standing valve 8, lower contact 9 compositions of leading to, upper connection 1 is connected with outer pump barrel 2, lower contact 9 is connected with outer pump barrel 2, outer pump barrel 2 is connected with interior pump barrel 3, equal diameter long-term job plug 6 is housed in the interior pump barrel 3, and the bottom of interior pump barrel 3 is connected with standing valve 8, is respectively arranged with upper travelling valve 5, lower travelling valve 7 in the equal diameter long-term job plug 6.
Have the two-way through hole 4 that leads on the interior pump barrel 3.
Two-way entire length of leading to the distance 〉=equal diameter long-term job plug 6 between through hole 4 and the standing valve 8.
The length of outer pump barrel 2 is greater than the length of interior pump barrel 3.
Upper connection 1 top is the box screw thread, so that with oil pipe pin thread scyewed joint on the pump, connect with outer pump barrel 2 outside the bottom of upper connection 1, connect with interior pump barrel 3 in the bottom of upper connection 1, interior pump barrel 3 bottoms are standing valve 8, in the interior pump barrel 3 is equal diameter long-term job plug 6, be upper travelling valve 5 on the equal diameter long-term job plug 6, equal diameter long-term job plug is for 6 times a lower travelling valve 7, the pump barrel wall of interior pump barrel 3 is provided with the two-way through hole 4 that leads to, and two-way distance of leading to through hole 4 and standing valve 8 equals or less times greater than the entire length of equal diameter long-term job plug 6, outer pump barrel 2 length are greater than interior pump barrel 3 length, outer pump barrel 2 bottoms connect with lower contact 9, and lower contact 9 can directly connect tail pipe under the pump.
