Corrosion Mechanism And Anticorrosion Of Gathering Pipeline In Tahe Oil Field

gathering pipeline, corrosion mechanism, anticorrosion, pipeline repair

【Abstract】 The corrosion of the gathering pipeline has become more and more serious because of its material In the environment of CO2-Cl- -H2O, strongly corrosive surrounding in Tahe oilfield. Analyzed the the Corrosion current situation, and constitutions of the produced water, Study of corrosion factor and anti-corrosion measure. Combined with application practice of technology in tahe oilfield, Countermeasure of pipeline repair are introduced. Suitability and economy of the technology in repairing gathering pipeline of oilfield are analyzed. Meanwhile, technical advantages of the technologies are summarized and improvement suggestions are proposed.
