Flange (2) in ratchet (1) is equipped with, the lower part of ratchet (1) is equipped with tooth (1.1), position in tooth (1.1), be equipped with opening (K) on flange (2), be equipped with through axle (4) articulated pawl (3) on opening (K), the inside of pawl (3) is equipped with tooth (1.1) equally, with tooth (1.1) the meshing on the ratchet (1), the outside center of pawl (3) is equipped with steel ball (5), pawl (3) are around axle (4) left side, turn right and move, realize the main story and the reversal of ratchet (1). The utility model is suitable for an in the oil field viscous crude thermal recovery production, 250 type production trees during with the steam injection 350 types annotate vapour well head sleeve pipe short circuit and change, solved the problem that the bolt burst out and frequently rotated afterburning thick stick direction, dismouting labour saving and time saving, convenient operation has improved work efficiency, alleviates operation workman's intensity of labour.
Description
Technical field
This utility model relates to oil-field thick-oil thermal recovery operation and changes casing short joint dismantling device, specifically a kind of wellhead casing pipe short circuit dismantling device.
Background technology
Heavy crude heat extraction produce in, because of
250
Type production tree cannot meet High Temperature High Pressure requirement, so needing during steam injection to change
350
Type special steam injection well head and casing short joint, turn and again change conventional production tree during pumping is produced and go into operation, and by High Temperature High Pressure in steam injection process, the impact of the factor such as corrosion is changed relatively difficult.The method that at present operation field is conventional has two kinds: one to be to plug two bolts oil pipes to turn a millstone the problem that formula shackle, this kind of method often occur oil pipe or bolt to burst out temporarily, there is potential safety hazard, and needs repeatedly to adjust work angle, and work efficiency is poor；Two is to use hydraulic disassembling device, and this instrument needs the casing coupling being embedded in underground is dug out and could be fixed, and this instrument volume is big, it is desirable to dig out around well head
1m

Between, and unshielded facility.There is installation to waste time and energy, operator's labor intensity is big, the problems such as Keep Clear-High Voltage.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, a kind of wellhead casing pipe short circuit dismantling device of design.
This utility model is realized by following technical proposals:
Wellhead casing pipe short circuit dismantling device includes: ratchet, flange, ratchet, axle, steel ball.The flange of described wellhead casing pipe short circuit dismantling device is built with ratchet, the bottom of ratchet is provided with tooth, position at tooth, flange is provided with opening, is provided with the ratchet hinged by axle on opening, and the inside of ratchet is again provided with tooth, engage with the tooth on ratchet, the outside hub of ratchet is provided with steel ball, and ratchet turns left and right around axle, it is achieved the main story of ratchet and reversion.
Ratchet top in above-mentioned wellhead casing pipe short circuit dismantling device is provided with afterburning hole, and center is provided with blind hole.
Flange in above-mentioned wellhead casing pipe short circuit dismantling device is " convex " font structure, and bottom is spherical crown shape, is respectively arranged at the two ends with three through holes.
Ratchet in above-mentioned wellhead casing pipe short circuit dismantling device is rhombogen.
The beneficial effects of the utility model are: be applicable to oil-field thick-oil thermal recovery produces,
250
Type Christmas tree wellhead sleeve pipe short with steam injection time
350
Type steam injection wellhead casing pipe short circuit is changed, and solves bolt and bursts out and frequently switch the problem in afterburning thick stick direction, and it is time saving and energy saving to dismount, easy to operate, improves work efficiency, alleviates the labor intensity of operating worker.
