Background
The wellhead assembly and well tools, such as lubricators, blowout preventers, etc., are assembled or disassembled below the injector head either before or after coiled tubing construction. The coiled tubing injection head is designed with an injection head support leg when leaving a factory, but the support leg length is fixed to be 1.5m and is only used when the injection head is inspected and maintained. If the construction tool is mounted and dismounted below the injection head, the existing supporting legs with fixed lengths are used, and because the height of the supporting legs is lower, an operator needs to work under the injection head by using the cat waist, the tool cannot be normally mounted in place or dismounted, time and labor are wasted, and the construction tool does not meet the requirement of human ergonomics; because the operating processes of the continuous oil pipes are different, blowout preventers or well-entering tools with different heights need to be connected below the injection head, the support height of the injection head is generally required to be 5m-15m, the height of the existing injection head supporting leg with the fixed length is limited and cannot be adjusted, and the operating requirements of different heights cannot be met at all. Under the condition that the supporting legs are not adjusted, generally, hoisting equipment (a crane) is used for hoisting the injection head to a proper height, then 3-5 workers install or dismantle the well entering tool under the injection head, and once the hoisting equipment sliding cylinder for hoisting the injection head is broken, or the injection head falls off under the conditions of a hoisting point, a steel wire rope sleeve and the like, the casualty accident is easily caused.
Therefore, the coiled tubing supporting leg with the fixed length is limited in height and cannot be adjusted, so that time and labor are wasted when a wellhead device and a well entering tool are mounted or dismounted under an injection head, and the requirement of construction operation cannot be met at all. And because hoisting equipment has the hoist and mount risk for the operation of removing to install of injection head has great potential safety hazard. Therefore, research a transport is light, the installation is swift, height-adjustable's coiled tubing injector landing leg, improves the injector and tears down the work efficiency who removes the installation instrument, reduces safe risk, has important realistic meaning.
