Description
Technical field
The utility model is related to fastening means technical fields, and in particular to a kind of casing recovery instrument.
Background technology
In current drilling operation at sea, shallow water operations block is particularly, probing is engaged in using self-elevating drilling platform and makees
During industry, in order to save drilling cost, the well that show value in exploratory well must produce directly is transferred to development well, will be used a kind of special
The mud line suspension system of door.The main purpose of this system is exactly to drill a well, needs to be transferred to development well after tested
In the case of, it dismantles at this system, without damaging casing programme, and well protection is got up, when exploitation is needed, profit
Production can be directly transferred to by being connected with tie back tool with well head.
In pervious operation, row recycling dismounting is anchored into using salvaging, it is to hang to carry using slip-type anchor fluke to salvage anchor
Casing is played, since this anchor fluke cannot rotate, dismounting every time is required for first lifting, and is then manually rotated, due to operation position
Limited between emptying, entire operation process is slow, and dangerous very big.Also there are some companies using steel wire rope lifting, manually revolve
Turn, be equally unable to solving practical problems.
It is to lift casing using the suspension of slip-type anchor fluke to salvage anchor, and hoisting power is very strong, but due to the tooth of this anchor fluke
It only stings upwards tight, it is impossible to rotate, dismounting every time is required for first lifting, and is then manually rotated, casing and following well head
Connection is screw-type, is generally had more than 12 teeth, and anchor is salvaged when rotation and then to be rotated, once rotation cannot be synchronous,
Salvaging the anchor fluke tooth of anchor will come off, and cause the damage or even injury to personnel of wellhead equipment, brought greatly to production operation
Risk and inconvenience.
Even if using steel wire rope lifting instead, since steel wire rope is flexible material, in rotary course, it may occur that torsion is played, and
Steel wire rope easily distorts in the case of stress, and difficulty is caused to rotation, dismantles operation every time, spends the time longer, and endangers
It is dangerous very big.
Therefore, how to design one kind makes salvaging anchor be consolidated with casing connection, rotation easily casing recovery instrument just into
For current urgent problem to be solved.
