Abstract

The working condition of medium in the Tahe Oilfield sewage treatment system is complicated and harsh, and the forced current cathodic protection technology can effectively control the station corrosion, prolong the service life and improve the oil removal efficiency. Based on the research method of combining theory with practice and taking into account the relevant domestic and foreign standards and codes, the calculation method of the forced current parameters, the selection of the auxiliary anode block and the selection of the potentiostat were put forward from the aspects of design, construction and evaluation. The installation position and form of the auxiliary anode block were introduced, the key points and requirements of the construction quality control were summarized, and the field application of the forced current cathodic protection technology was analyzed and discussed. Besides, its applicability in Tahe Oilfield was analyzed from three levels: pre - application necessity analysis, field parameter determination and effect evaluation. It was proved that after applying the above - mentioned technology, the corrosion problem of sewage treatment system was effectively controlled, the safe and stable operation of the oil and gas processing system was ensured.
