The most common problem of API 5CT K55 tubing and casing is corrosion. How to avoid this problem that is a very important problem. Katalor is a famous API 5CT K55 tubing and casing supplier and exporter in China. We have a strict quality control system of API 5CT K55 tubing and casing.
1. First of all, the water quality should be well qualified, and the water quality should be tested and managed strictly. To carry out decontamination and separate injection, strengthen the cleaning of main water API 5CT K55 tubing and casing, achieve the quality of water in the station and at the bottom of the well to meet the standard, and reduce the introduction of corrosion sources into the annular space.
2. For the newly put into operation water injection wells, use circular-air protective liquid in API 5CT K55 tubing and casing, which is mainly used for adding sterilization, and form a system to add on a regular basis.
3. In view of the accelerating effect of mechanical abrasion on the corrosion of petroleum casing, it is recommended to add a rubber ring to the API 5CT K55 tubing and casing coupling or a centralizer at the serious location of borehole inclination to avoid scratching the API 5CT K55 tubing and casing sleeve and one side contact casing during operation and water injection.
4. For severe bacterial corrosion under scale and slow growth and killing of SRB at high temperature, it is feasible to inject water or water vapor of 100 degrees celsius into the API 5CT K55 tubing and casing annular space periodically to kill SRB under scale.
5. It is not recommended to popularize the use of cathodic protection and coated casing before the corrosion in the casing of API 5CT K55 tubing and casing injection well is effectively controlled.
