Optimal Selection of Hydrogen Sulfide Inhibitors in Offshore S Oilfield and Its Application
To solve the problem of high H2 S production in the offshore oilfield S,which affects the safety production of the oilfield,a comprehensive analysis of the reservoir,fluid,and microbial properties is conducted to determine the cause of H2 S in the oilfield,and a H2 S inhibitor optimization experiment is carried out.The research results in-dicate that the laboratory experiment evaluation of hydrogen sulfide inhibitor TS-762 shows good desulfurization effect,and TS-762 has good compatibility with chemical agents used in production water treatment systems.The application results of the field practice show that TS-762 can effectively exert the biological competitive exclusion effect,and the H2 S concentration produced by the production wells in the block is significantly reduced.
