Steel Cold Rolled Oil Cone Pipeline grade: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc.. The end of the casing processing forms: short round thread, long thread, buttress thread, special buckle etc.. Anticorrosion measures of oil casing 1 . First do a good job of water quality standards, strict water quality testing and management. The implementation of the clean water injection, to strengthen the main water pipeline cleaning work, so that the station within the bottom of the water quality standards, reduce the erosion of the introduction of ring space; 2. On the newly put into operation of the water injection well, take to add the sterilization based annulus protection liquid, and the formation of the system, regular investment plus; 3. In view of the mechanical abrasion of oil casing corrosion acceleration effect, it is recommended in tubing hoop with a rubber ring or add a centralizer in the severe deviation location, to avoid in the operation process and the process of water injection tubing scrape injury casing and contacts to one side of the casing; 4. In the case of severe bacterial corrosion under the scale and high temperature SRB slow growth and kill, can be regularly to the ring air injection of 100 degrees Celsius water or water vapor to kill the scale of SRB; 5. The corrosion of the casing in water injection well is not under effective control, and is not recommended to promote the use of cathodic protection and coating.
