Description
Technical field
The present invention is the underground equipment of oil field operation, is a kind of releasing device.
Background technology
Implement to need for downhole tool to be divided into two parts, one in well when separate layer acid treatment pressure break and zonal water plugging operation
Divide and propose to come onto well, a part stays in instrument in well.Downhole tool is divided into two-part instrument in well and is referred to as dress of giving up
Put.Current releasing device come with some shortcomings part, distinct issues be rear releasing gadget is buried by sand and debris will
Failure, the problem for occurring giving up causes construction to fail, and produces heavy economic losses.
The content of the invention
The purpose of the present invention is a kind of releasing device of design, can reliable releasing, raising construction success rate.
The object of the present invention is achieved like this：Including top connection of giving up, lower contact of giving up, closing piece, shear pin of giving up, upper close
Seal, middle sealing ring, release pipe, lower seal, unblock shear pin, overcoat, spring, lower contact, the bottom of top connection of giving up are installed
In lower contact top of giving up, shear pin of giving up is arranged on top connection of giving up, gives up in lower contact, has on the outer wall of top connection of giving up
Locked groove, there is lock window in lower contact of giving up, lock window correspondence locked groove places closing piece locking in window, the inwall of closing piece connects on giving up
In locked groove on the outer wall of head, give up and sealing ring is installed between top connection and lower contact of giving up, upper sealing ring is in give up and cuts
Release pipe, spring are set with nail, outside lower contact of giving up, the inwall for discharging pipe encases closing piece, prevents closing piece from being displaced outwardly, loses
There is linked hole in the middle part of subordinate joint, linked hole is under upper sealing ring, give up and sealed in being installed between lower contact and overcoat
Circle, lower seal, middle sealing ring are on linked hole, and lower seal is under linked hole, give up lower contact and overcoat it
Between annular space is formed by diameter difference, annular space is between middle sealing ring, lower seal, between the inside of annular space and lower contact of giving up by
Linked hole UNICOM, the bottom of lower contact of giving up is connected with the top of lower contact, spring is between release pipe and lower contact, releases
Putting has release groove in pipe, release groove is under closing piece, and the height of the height more than closing piece of release groove, coat suit is managed in release
Outward, the top of overcoat is connected with the top of lower contact of giving up, and unblock shear pin is arranged on release pipe and puts outward.
The beneficial effects of the invention are as follows：Need the parts of work to be in the inside not buried when giving up, inside base both
Make to be buried by miscellaneous spy, the parts of work are needed when giving up can also be acted by the requirement of design, therefore, the present invention can reliably lose
Hand, can improve construction success rate, with significant economic benefit.
Brief description of the drawings
Accompanying drawing is the installation diagram of the embodiment of the present invention.
Specific embodiment
Embodiments of the invention are illustrated below in conjunction with the accompanying drawings.
As illustrated, embodiments of the invention include give up top connection 1, lower contact 2 of giving up, closing piece 3, shear pin 5 of giving up, on
Sealing ring 6, middle sealing ring 7, release pipe 9, lower seal 11, unblock shear pin 12, overcoat 13, spring 14, lower contact 15, give up on
The bottom of joint 1 is arranged on and gives up in the top of lower contact 2, and shear pin 5 of giving up is arranged on top connection 1 of giving up, gives up in lower contact 2,
Give up top connection 1 outer wall on have locked groove, have lock window in lower contact 2 of giving up, lock window correspondence locked groove places closing piece 3 locking in window,
In the locked groove that the inwall of closing piece 3 enters on the outer wall of top connection 1 of giving up, the top connection 1 that makes to give up, lower contact 2 of giving up are locked in one
Rise, the axial force of bottom can be accepted, the inwall upper and lower ends of closing piece 3 are the conical surface, and corresponding locked groove upper and lower ends are also cone
Shape face, is given up and sealing ring 6 is installed between top connection 1 and lower contact 2 of giving up, and upper sealing ring 6 is under shear pin 5 of giving up, and is lost
The outer suit release pipe 9 of subordinate joint 2, spring 14, the inwall for discharging pipe 9 encase closing piece 3, prevent closing piece 3 from being displaced outwardly, will lose
Joint 1, lower contact 2 of giving up on hand is pinned, and there is a linked hole 8 at the middle part of lower contact 2 of giving up, linked hole 8 be in upper sealing ring 6 it
Under, sealing ring 7, lower seal 11 in being installed between lower contact 2 and overcoat 13 of giving up, middle sealing ring 7 are on linked hole 8,
Lower seal 11 is under linked hole 8, to be given up and form annular space 10 by diameter difference between lower contact 2 and overcoat 13, at annular space 10
Between middle sealing ring 7, lower seal 11, by the UNICOM of linked hole 8 between the inside of annular space 10 and lower contact 2 of giving up, give up down
The bottom of joint 2 is connected with the top of lower contact 15, spring 14 is between release pipe 9 and lower contact 15, and spring 14 has one
Fixed pretightning force, there is release groove 4 in release pipe 9, release groove 4 is under closing piece 3, the height of the height more than closing piece 3 of release groove 4
Degree, it is ensured that closing piece 3 can depart from top connection 1 of giving up, overcoat 13 is sleeved on and discharges outside pipe 9, the top of overcoat 13 and lower contact 2 of giving up
Top connection, unblock shear pin 12 is arranged on release pipe 9 and overcoat 13.
First inwardly suppressed before giving up, pressure is through in the incoming annular space 10 of linked hole 8, pressure promotes release pipe 9 to cut unblock and cuts
Nail 12, after cancelling pressure, the pretightning force of spring 14 promotes release pipe 9 up, release groove 4 is directed at closing piece 3, and closing piece is two about 3
There is taper surface at end, and outwardly radial power is produced under responsive to axial force, and making the outer wall of closing piece 3 is carried out in release groove 4, closing piece 3
Inwall departs from the locked groove of top connection 1 of giving up, then above proposes top connection 1 of giving up, and shear pin 5 of giving up is pulled off, give up top connection 1 with give up
Lower contact 2 departs from, and realizes giving up.
