Casing is important to oil drilling equipment, and its main equipment includes drill, core pipe and casing, drill collars and drilling small diameter steel pipe, and so on.
1, first of all, the quality of water standards, strict water quality testing, and management. The implementation of decontamination, strengthening the cleaning of the main water pipeline, to achieve the station, the bottom of the well water quality standards, reduce the introduction of corrosion sources into the ring space;
2. For the newly put-into-operation water injection Wells, the annulus protective fluid mainly for injection sterilization shall be adopted, and a system shall be formed for regular injection
3. In view of the acceleration effect of mechanical abrasion on the corrosion of oil casing, it is recommended to add a rubber ring on the tubing coupling or a centralizer on the severely inclined part of the well, so as to avoid the tubing scratching the casing and one side contacting the casing during the operation and water injection process;
4. In view of the serious corrosion of bacteria under scale and the slow growth and killing of SRBS at high temperature, high-temperature water or steam at 100 degrees Celsius can be injected into the annulus regularly to kill SRBS under scale;
5. It is not recommended to popularize the use of cathodic protection and coated casing before the corrosion in the casing of the injection well is effectively controlled.
