Power.
The installation method of running tool and large diameter hanger is during use：Hanger needs before mounting seat big envelope 201
Running tool is first connected, running tool is not installed joint 101, fluid cylinder 102, piston 104, power transmission set 105, second temporarily and cut
Nail 106, set 109 is promoted, running tool is corresponding with the upper end of hanger central tube 204 by the left-hand thread screw thread on block 115 of giving up
Left-hand thread is threaded togather, and is inserted in setting set 201 afterwards, then installation promotes the shear pin 106 of set 109 and second successively, is inserted in work
Plug 104, fluid cylinder 102 and top connection 101 are finally installed, complete the installation of hanger complete machine.Now, sealing device 119 forms ball
Sealing between seat 120 and hanger central tube 204；
The course of work is described as follows：Top connection 101 connects drill string, and lower contact 218 connects expandable screen or other completion tubulars
String, instrument is sent into well by drill string, under in place after pitching establish pipe interior sealing environment to the position of ball seat 120, connect pump truck and beat
Pressure, pressure are passed in running tool by drill string, and pressure is set multiple logical on the tube wall by running tool central tube 103
Hole is acted on piston 104, and hydraulic coupling is passed to power transmission set 105 by piston 104, and hydraulic coupling reaches the first shear pin after certain value
107 cuttings, power transmission set 105 move downward, and control closing piece 108 enters the second segment of power transmission set 105, control closing piece 108 from feeding
The second segment into power transmission set 105 is skidded off in tool focus pipe 103；The unblock of control set 110, as power transmission covers 105 slide downwards,
Control closing piece 111 slides from the first boss of running tool central tube 103, and it protrudes the part of second boss, and to submerge second convex
In platform, setting set 201 is unlocked；Promotion set 109 pusher seat big envelope, the 201 setting hanger body in the outside of power transmission set 105, specifically such as
Under：The setting drive of set 201 packing element set 203, packing element cap bag 208, adapter sleeve 206 and upper cone 209 move downward, the 5th shear pin
211 are cut, and inclined-plane of the tub slips 212 along upper cone 209 and lower cone 213 extends out expansion, stings tight set tube wall, are realized to sit and are hung
Function.The power that setting set 201 provides further increases, and cuts the 4th shear pin 207, and packing element set 203 continues to move downward, packing element
205 packing element cover 203 inclined-planes in the presence of be in bowl-shape expansion, be adjacent to internal surface of sleeve pipe and realize sealing function.Simultaneously under packing element set 203
The packing element cap bag 208 of end connection can be moved and pushed up on upper cone 209, further be pressed by the conical surface to tub slips 2-12,
Increase the anchorage force of hanger.Setting set 201 is locked, it is ensured that work while action by the step-by-step movement of lock ring 202 with gingival cyst of mucous gland in the newborn button
Tool will not unseal in advance.
Hanger is sat hang after the completion of, further increase the pressure in running tool central tube 103, cut promote set 109 with
The second shear pin 106 between power transmission set 105, power transmission set 105 can move forward, power are transmitted into helmet 113, then transmitted
To stop collar 114 of giving up, the stress of stop collar 114 of giving up is cut the 3rd shear pin 117 and moved downward, and block 115 of now giving up can be in plate
Inwardly retracted into the presence of spring 116 in the groove I for stop collar 114 of giving up, release give up block 115 and hanger central tube
Connection between 204, realize by the function of giving up of fluid power, while when piston 104 moves to the bottom of fluid cylinder 102, piston 104
Gap between fluid cylinder 102 releases sealing, abrupt pressure reduction occurs and give up signal and to establish circulation.If hydraulic releasing not into
Work(, the threaded connection of give up block 115 and hanger central tube 204 by rotating forward drill string, can also be released, realize that machinery is given up work(
Energy.
The hanger to salvage function implementation process as follows：Later stage tripping in specific purpose tool salvages hanger, specific purpose tool
It is inserted into hanger central tube 204 to establish with its left-hand thread screw thread and connects, specific purpose tool lower end is provided with hook, can hook salvaging limit
The inner groovy at the middle part of position set 217, hook are moved downward by hydraulic coupling, are transmitted the force to and are salvaged stop collar 217, cut shear pin
216, salvaging stop collar 217, which moves downward, drops down onto the position of lower contact 218, and stop collar 217 promotes lower contact 218, drives the company of salvaging
Female connector 214 moves downward, and because screw thread claw 215 loses the support of stop collar 217, its underpart is hanging, salvages adapter sleeve 214
Screw thread claw 215 bounces back when moving downward, and is disengaged with salvaging adapter sleeve 214；Now salvage adapter sleeve 214 and drive lower cone 213
Move downward, the lower end of tub slips 212 releases grappling to contract.Then specific purpose tool is above carried, drives hanger central tube 204
Motion upwards, hanger central tube 204 drive the motion upwards of setting set 201, while drive the motion upwards of packing element set 203, packing element
205 lose the backward contract deblocking of support of packing element set 203, while the packing element cap bag 208 being connected on packing element set 203 drives and connected
Female connector 206 is moved upwards with upper cone 209, and the upper end of tub slips 212 releases grappling to contract.Continue above to carry specific purpose tool,
