The Research of Corrosion Mechanism and Protection Measure of WaterfloodPipes

摘要

The corrosion mechanism of sixteen waterflood pipes of Nanbu Oilfield have beenrnresearched through a series of in-house experiments, and the dominant elements thatrncause the corrosion are revealed, the two elements are the hyper salinity and highrncorrosive ion content of the injected water quality. And the corrosive degree of everyrnwaterflood pipes are contrasted in the same condition, the technique measure thatrnappropriate pipes are selected first and then adequate anti-corrosive agent are adaptedrnis futher put forward. So the well control of corrosion of waterflood pipes can bernrealized, and there is an important instructing meaning for the production of NanburnOilfield.
