In the current oil production, the amount of oil produced has increased greatly, and the number of inclined Wells used for current oil production has also increased, and preventing corrosion of oil pipelines has become very difficult. In addition, there is the use of the oil pipeline environment, its environment is a high temperature and high pressure environment, there are also easy to corroded substances. Therefore, the loss of the pipeline in the mining process is also very large.
Oil pipelines in cold or hot weather will occur spontaneous combustion aging, if the aging of oil pipelines will not only affect the normal running of the car, but also cause spontaneous combustion, so it is necessary to plug the leak and repair them as soon as possible. So the tubing pup joint came into being.
After several years of use, it is often necessary to loosen the screw, and there will inevitably be a snap phenomenon, such as the oil pan screw of the gearbox must be unscrewed every time it is replaced. Before shorting the tubing, wipe the tubing with a dry cloth and the outside of the socket. When the surface is sticky or not sticky, it needs to be wiped clean with acetone.
The cross-section of the tubing pup joint should be smooth, and insertion marks should be drawn before shorting, and experimental insertion should be conducted. Tubing shorting first requires the release of the part connected to the pipe and then the clamp holding the pipe in place to ensure that the metal cover of the pipe is properly connected to the joint of the connecting part.
Connect the pipe to the component connector, then tighten the screw holding the sensor with the tool belt, tighten the loosened clip above, and press the torque three times to ensure that the pipe is in good contact with the sealing surface of the component connector.
In order to ensure the time benefit of construction, a new coiled tubing shorting technology is adopted and the pup joint is conducted at the overflow point of tubing. The technical maintenance branch is repeatedly verified. The process can be constructed at room temperature, without ignition, easy to operate, and has the advantages of room temperature curing, simple process, convenient construction, fast curing time, etc.
