State sealing test passage axially penetrating through along the tool body 1, and the upper end of the sealing test passage and the sealing test
Sealing joint connects, and the lower end of the sealing test passage is located at the lower face of the bottom of the tool body 1.
The underwater production tree cup running tool of above example, two parts up and down, upper and lower two parts are segmented into by function
It is serially connected by tool body.Wherein, lower part is by lower baffle ring 2, emergent unlock base 3, drive ring 4, retaining ring 5, anti-rotation
Key block 9, plug screw 10 and lag screw 11 are formed, and major function is to realize underwater production tree cup running tool and underwater production tree cup
Locking and unlock；Top is mainly made of upper baffle ring 6, driving piston 7 and stress bolt 8, and major function is to realize to adopt under water
Installation locking between oil tree cap and underwater horizontal type production tree.Have the advantages that simple and compact for structure.
The use process of the underwater production tree cup running tool of above example is as follows：
First, underwater production tree cup running tool need to be connected with underwater production tree cup.
During connection, by the rotation of the tool body 1 of underwater production tree cup running tool, the spiral shell on driving instrument body 1
The drive ring 4 of line connection, drive ring 4 is gradually moved into 5 inner ring of retaining ring, and retaining ring 5 is strutted, and makes the outer ring of retaining ring 5
It is caught on the lubrication groove profile face of underwater production tree cup and locking is realized in corresponding card slot.
Considered in design underwater production tree cup running tool may rotation, so, be provided with retaining ring 4 anti-
Turn key block 9, anti-rotation key block 9 are caught in the keyway of the underwater production tree cup to match therewith, realize anti-rotation function.
Secondly, promote underwater production tree cup to install with underwater horizontal type production tree to connect.
During installation, since the inside of tool body 1 is hollow structure so that the tool body of underwater production tree cup running tool
There are pressure difference inside and outside 1, press to annular space outside underwater production tree cup running tool, driving driving piston 7 breaks stress bolt
8, and promote the ring that actuates of underwater production tree cup to move down and promote the retaining ring of tree cap body radially distending, realize
Locking connection between underwater production tree cup and underwater horizontal type production tree.At the same time, underwater production tree cup running tool is in work
When making, the movement of piston 7 is driven, promotes the fluid in plunger shaft to be flowed into by runner hole 12 in tool body 1, when driving piston
7 when being moved to the displacement specified, and portion of runner hole 12 connects the inside of tool body 1 with outside, releasing appliance body 1 it is interior
External differential, while shown in remote control terminal（Measured for measuring the pressure sensor of inner pressure inside pipe）, realize
The effect of instruction is installed in place, improves the control accuracy of installation.
Finally, the connection of underwater production tree cup running tool and underwater production tree cup is released.
Control drilling rod, which rotates, drives tool body 1 to reversely rotate, during rotation drive ring 4 under the action of screw thread to moving up
Dynamic, the inner ring of retaining ring 5 does not stress and elastic recovery occurs, and it is real that 5 outer ring of retaining ring departs from underwater production tree cup lubrication groove profile face
Now unlock.So as to which underwater production tree cup running tool is smoothly withdrawn.
In addition, the present invention will be additionally provided with the emergent unlocking function of machinery.The emergent unlocking function is rotated when by drilling rod
Tool body 1 can not make it that drive ring 4 retracts and so that retaining ring 5 uses when retracting, in use, passing through overpull hoisting tool sheet
Body 1, breaks the lag screw 11 of tool bottom, is dropped down onto under emergent unlock base 3 at caging bolt, and lower baffle ring 2 is with putting with seat
Sleeve 3, which falls, segment distance and enables the retaining ring 5 on lower baffle ring 2 away from drive ring 4, so as to realize production tree
Emergent unlock between cap installation tool and underwater production tree cup.
