| Abstract: | Ever since 1998, corrosion of drill rod and minor corrosion leakage have occurred in Pinghu oil Field in East China Sea. 11 different experiments have been conducted with participation of different sciences and specialties. The corrosion damage of the drilling equipment is resulted from combined effect of a number of factors including a little amount of H 2S present in oil deposit. All these provide a very good information for determining proper corrosion protection grade and prediction of the service life of the production equipment. |
