In terms of the bearing capacity of the oil casing pipe, it is relatively difficult for designer and professionals to judge the interference of some important factors on the strength of the oil casing pipe.
In the application, the interference caused by reasons such as the uneven bearing capacity of the casing pipe for oil well drilling is comprehensively considered, which may greatly reduce the bearing capacity of the oil casing pipe. Therefore, it is extremely important to analyze the interference of these important factors on the strength of the oil casing pipe.
Under normal circumstances, pour corrosion and scale inhibitors into the annular range of oil and gas wells to adjust the pH value and adopt closed oxygen isolation technology. It is mainly to solve the problem of corrosion inside the oil casing pipe. For the problem that the surface of the oil casing pipe is corroded, generally the technology of regular maintenance of cathode is used.
Regular maintenance of the cathode of casing pipe for oil well drilling is an economical, reasonable and effective maintenance measure to prevent soil corrosion of the underground steel structure frame. The cathode regular maintenance is a perfect and safe anti-corrosion technology, which has the characteristics of strong functions, very simple construction and low capital investment.
Manufacturers of oil casing pipe show that this type of technology has been more and more comprehensively applied in the petrochemical and petroleum and natural gas industries. The cathode regular maintenance technology can not only prevent the corrosion of the oil casing pipe, and at the same time, it is also particularly reasonable and effective for the newly-built oil casing pipe. It can also increase the service life, reduce the number of replacements, and have significant social and economic benefits.
