Shape, by fluid power shaping tool expanded casing inwall, make up to standard.Current unfreezing fishing instrument and shaping tool are most
Completed by mechanical forces, and the two general can not be salvaged or shaping, it is necessary to prepare different instruments, complex operation, into
This height.
The content of the invention
In order to overcome the shortcomings of existing underground unfreezing fishing instrument and shaping tool can not it is general, cost is high, this practicality
A kind of new fluid power of offer is salvaged and shaping tool, and the fluid power is salvaged and shaping tool is controlled by fluid power, can realize underground respectively
Unfreezing fishing and shaping, reduce cost.
The technical solution of the utility model is：A kind of fluid power is salvaged and shaping tool, including lower contact, top connection, described
Lower contact top connects cylinder body, and pressure release tip-lever support is connected inside lower contact, and pressure release push rod is connected inside pressure release tip-lever support, described
Cylinder body is divided into some sections, is connected between every two sections by joint, and ball seat piston, ball seat internal piston bottom are provided with inside cylinder body
End connection valve ball seat, valve ball seat bottom connect lower spring cup by holding screw, and lower spring cup top is provided with spring, spring
Top is provided with upper spring seat, and upper spring seat top is provided with valve ball, steel is connected with above the ball seat internal piston valve ball
Ball stopper circle, and it is provided with liquid pass hole on steel ball back-up ring；Piston rod, the connection of piston rod upper end are connected with above the ball seat internal piston
Keyway body, keyway body top are connected with top connection, connecting key barrel outside keyway body, and keyway pipe lower end passes through joint and oil cylinder
Body phase connects.
The utility model has the advantages that：Due to taking such scheme, the instrument is connected under different tubing strings,
Controlled by fluid power, can realize underground unfreezing fishing and fluid power shaping respectively, lifting force is big, safe during unfreezing, applies during shaping
The work cycle is short, applied widely, and repairing casing form consolidates.Cost thus is reduced, there is obvious economic benefit.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of fluid power salvaging and shaping tool, including lower contact 1, top connection 19, the top of lower contact 1
Cylinder body 14 is connected, is fastened between lower contact 1 and cylinder body 14 by screw.The inside of lower contact 1 connection pressure release tip-lever support 2, pressure release
The inside of tip-lever support 2 connection pressure release push rod 3, and it is provided with longitudinal hole on pressure release tip-lever support 2.The cylinder body 14 divides for some sections, often
It is connected between two sections by joint 16, the inside of cylinder body 14 is provided with ball seat piston 12, is set between ball seat piston 12 and cylinder body 14
There is sealing ring.The inner bottom of ball seat piston 12 connection valve ball seat 6, the bottom of valve ball seat 6 connects lower spring by holding screw 4
Seat 5, the top of lower spring cup 5 is provided with spring 8, and the top of spring 8 is provided with upper spring seat 9, and the top of upper spring seat 9 is provided with valve ball 10,
The top of the inside valve ball 10 of ball seat piston 12 is connected with steel ball back-up ring 11, and the upper end of steel ball back-up ring 11 passes through ball seat piston 12
Step on inwall is spacing, and is provided with liquid pass hole on steel ball back-up ring 11.The inner upper of ball seat piston 12 is connected with piston rod
13, piston rod 13 has some, is connected between every two by joint, the upper end connecting key cell body 18 of piston rod 13 of the top,
The top of keyway body 18 is connected with top connection 19, the external connection keyway pipe 17 of keyway body 18, and the lower end of keyway pipe 17 passes through joint 16
It is connected with cylinder body 14.
When needing to salvage trouble of lost tool in hole, the top connection 19 of the instrument is connected to oil tube anchor device lower end, the lower end of lower end 1
Connect fishing tool.Running string, suppressed out of tubing string, due to being sealed between valve ball 10 and valve ball seat 6, pressure in tubing string
Increase, promote piston rod 13 to move up, make oil tube anchor device spreading, fishing string is anchored on sleeve pipe；Continue to suppress, hydraulic pressure exists
Reinforcement is acted at part, and pulling force is produced at fishing tool, moves trouble of lost tool in hole.An impulse stroke is completed when mobile
Afterwards, tubing string is no longer suppressed, then valve ball 10 moves up under the elastic force of spring 8, is opened passage, automatically unloading, is grasped to well head
One signal of author, meanwhile, oil tube anchor device automatically retracts；Upper lifting pipe post, tool portions are resetted, continue to repeat above mistake
Journey, until the complete unfreezing of trouble of lost tool in hole.
When carrying out shaping well workover, the instrument is turned upside down use, i.e. upper, top connection 19 above connects under for lower contact 1
First 19 lower end connects reducing expander, running string, is suppressed out of tubing string, and fluid power promotes valve ball 10 to move down, and overcomes bullet
The elastic force of spring 8, promote the steel ball on reducing expander progressively expanding, reducing casing tube is carried out under the lasting promotion of fluid power expanding
And roll simultaneously, sleeve pipe is rolled back circle and progressively recover latus rectum；After pressure release, valve ball 10 under the spring effect of spring 8 from
It is dynamic to withdraw.By expanding rolling repeatedly step by step, sleeve pipe progressively Hui Yuan, so as to realize the expanding shaping of casing deformation well section, reach requirement.
