Description
Technical field
The present invention relates to dismounting joint field, and buckle and latchplate is cut more particularly, to one kind torsion.
Background technology
Recently as land oil exploitation yield reduce sharply and the increase of cost of winning, country add marine oil and gas and surveyed
Exploitation dynamics is visited, the application and exploitation of marine riser also enter crucial moment.Surface pipe is that drilling well obtains the first of petroleum and gas resources
Layer barrier, serve the extraneous mud of isolation, sand, seawater, the not contaminated vital effect of protection sleeve pipe oil gas.At sea bore
During spy, reservation or tieback well head are needed after verifying oil and gas reserves, facing mud line nearby needs to cut marine riser with hydraulic cutter,
Complex operation, operating cost are high.
The content of the invention
It is an object of the invention to be solution the deficiencies in the prior art, and a kind of turn round is provided and cuts buckle and latchplate.
The new technical scheme of the present invention is：One kind is turned round and cuts buckle and latchplate, including female joint, pin end, sealing ring and
Pin is cut, described female joint includes locating slot, anti-rotation groove and pin locating holes, and described locating slot, anti-rotation groove connect, and
Locating slot internal diameter is more than anti-rotation groove internal diameter, and locating slot, 360 ° of anti-rotation groove are distributed in female joint, and female joint positions provided with pin
Hole；Described pin end includes hanging block, seal groove and cuts cotter way, and 360 ° described hanging block, cutting of cotter way are distributed on public affairs
On joint, pin end is provided with seal groove, is sealed using sealing ring during assembling；Described pin end is fixed on mother by hanging block
In the locating slot of joint, anti-rotation groove；Described cutting pin is with cutting cotter way, pin locating holes match, and break pin, which nails on, to be set
There is cutting line.
Described hanging block, to cut cotter way be 4.
Described locating slot, anti-rotation groove are 4.
Described pin locating holes are 1.
Described sealing ring is O-shaped nitrile rubber.
Described break pin is nailed on chamfering.
Described pin end, female joint are coordinated using multi-step.
Described pin end, female joint material are Q345D, 20Mn2,30CrMo, 4130 and other material forging etc..
It is Φ 406mm~Φ 914mm that described pin end, female joint, which are adapted to casing diameter scope, casing wall thickness
12.7mm~38mm.
Beneficial effects of the present invention are：1）Save operating cost.The device can realize that marine riser is quick near mud line
Dismounting, avoid causing marine riser to scrap with hydraulic cutter cutting, complete riser joints can be retained, facilitate secondary recovery to make
With avoiding the waste of marine riser product, saved probing cost of winning.
2）Installing/dismounting speed is fast.Male and female joint only need to rotate 160mm or so after coordinating to be installed in place, and equally tear open
Upper lifting pipe string when unloading, pin is cut in reversion can realize dismounting, substantially reduce the drilling engineering activity duration.
3）Properties of product are reliable.It is high to hang bulk strength, tension, bending resistance, the internal pressure strength of joint are above body, break pin
Nail has certain anti-rotating function, and shearing resistance moment of torsion is 23000Ib-ft, and multi-functional makes product structure stabilization, dependable performance.
4）Good seal performance.Sealing ring material uses nitrile rubber, have it is anticorrosive, temperature resistant range is big, anti-aging feature,
Internal pressure reaches 18.3MPa, has ensured the sealing property and durability of product.
In summary, a kind of turn round that we research and develop cuts that buckle and latchplate performance is excellent, and not only avoid prospect pit needs
The complicated process of marine riser is cut with hydraulic cutter, while avoids the wasting of resources, has saved operating cost, is had well
Generalization.
