Briefly understand the technology and precautions of gas wells under pressure

Pressurized operation mainly refers to an operation method in which professional and technical personnel operate special equipment to lift and lower the pipe string in a pressurized environment. The pressurized operation device for gas wells is one of the widely used technologies in oilfield downhole operations.

The specific operation method is that in the process of downhole operations, technicians effectively apply some special workover equipment, so that the wellhead of the oil field well will be under pressure. On the basis of this phenomenon, downhole operations can be carried out. Effective exploitation of underground petroleum resources.

Downhole pressure operations in an oil field mainly include workover operations, rescue operations, completion operations, and sidetracking operations, etc. There are also few other tasks.

The following points need to be paid attention to in the technology of downhole pressure operation equipment in oil field

First, it is necessary to effectively control the oil sleeve ring air pressure scoop in downhole operations, which can be achieved through the effective application of the blowout preventer group.

Secondly, it is necessary to master and apply the clogging technology so that the pressure inside the tubing can be controlled to avoid other adverse effects.

After that, special attention needs to be paid to the technique of applying external force to the tubing string, and reasonable pressure is applied to the tubing string, so as not to be affected by the upward force in the well, which will damage the downhole pressure operation. The tubing string will cause the tubing Carry out the action of lifting and lowering, so as to ensure the smooth progress of the downhole mining operation in the oil field.

Downhole pressure operations in oil fields have the advantages of strong safety and good environmental protection effects.
