What are the precautions for using oil casings?

- Dec 12, 2020-

What are the precautions for using oil casings? The oil casing is used to support the oil and gas well walls to ensure the normal operation of the entire well after the drilling process is completed. Each well is based on different depths of drilling and geology, using several layers of casing. After the casing is down, the cement is to be cemented. It is different from the oil pipe and the drill pipe and cannot be reused. It is a disposable material.
1. First of all, we must do a good job in water quality compliance and strict water quality testing and management. Implement decontamination and re-injection, strengthen the cleaning of the main water pipeline, achieve the standard water quality in the station and the bottom of the well, and reduce the introduction of corrosion sources into the annular space;
2. For the injection wells that have been newly put into operation, adopt an annulus protection liquid based on dosing and sterilization, and form a system to regularly add;
3. In view of the mechanical scuffing to accelerate the corrosion of the oil casing, it is recommended to add a rubber ring to the tubing coupling or add a centralizer to the serious part of the well to avoid the oil pipe from scratching the casing during the operation and water injection. One side contact sleeve;
4. In case of severe bacterial corrosion under scale and slow growth and killing of SRB at high temperature, periodically inject 100 degrees Celsius of high temperature water or water vapor into the annulus to kill SRB under scale;

5. It is not recommended to promote cathodic protection and coated casing before corrosion in the casing of the injection well is effectively controlled.
