Study on Optimization of Anticorrosion Technology for Valve Pit Facilities in Tahe Oilfield

Abstract

Due to the abundant underground water source, the structure of the valve pool, the non installation of water stop flange in the crossing pipeline and other problems, the leakage disease rate of the valve pool in Tahe oilfield reaches more than 80%. If it is not treated in time, the valves, pipe fittings and other facilities will be rusted, which will affect the normal operation and daily maintenance of the valves and cause serious potential safety hazards. According to the characteristics of the valve pool in Tahe oilfield, XinJiang, the performance and construction technology of different kinds of anti-corrosion materials are studied, and the best anti-corrosion materials are optimized. Through comparative research, it is found that the multi-layer petrolatum coating technology has excellent anti-corrosion performance and simple construction technology, which can completely solve the corrosion problem of the pipe fittings inside the valve pool.
