合水油田注清水系統(tǒng)腐蝕機(jī)理及防護(hù)措施研究
[Abstract]:With the continuous development of Heshui Oilfield, pipeline corrosion of clean water injection system in Heshui Oilfield is becoming more and more prominent. Among them, Zhuangyi injection, Zhuangliu injection water pipeline and Zhuanger second injection pipeline, the pipeline corrosion in Zhuang3 injection station is very serious, and perforation occurs frequently. The serious corrosion of pipeline in water injection station not only shortens the service life of water injection pipeline, increases the operating cost and environmental pressure of the enterprise, but also has a serious impact on the normal production of the enterprise, resulting in the waste of social resources. The purpose of this paper is to analyze the water quality and solid corrosion products of various corrosion stations in a comprehensive and scientific way, to summarize the main causes of pipeline corrosion, and to speculate on the possible corrosion mechanism. On this basis, the target corrosion inhibitor with good corrosion inhibition effect is selected, and the adaptability evaluation of the selected inhibitor is carried out to realize the effective anticorrosion protection of the water injection pipeline in Heshui Oilfield.
