Study on corrosion control scheme of oil pipe in injection well of Bohai oil field
The oil pipe corrosion of an oil injection well in Bohai oil field is serious.According to the characteristics and corrosion condition of the oil injection well,the applicability of the oil injection well is studied.In particular,the systematic study on the galvanic corrosion of N80 and several kinds of anti-bacterial pipe,3Cr,5Cr,9Cr,13Cr combined pipe,as well as the technical optimization of combined pipe and the selection of coating technology was carried out.In view of the local corrosion of the pipe string in this oilfield,the effective corrosion control scheme of the combined pipe is proposed,which has important guiding significance for the subsequent corrosion control of water injection Wells.
