摘要
海上S油田硫化氢(H_(2)S)产出浓度高,影响油田安全开发生产。为解决此问题,通过综合分析S油田储层、流体及其菌群性质,确定油田H_(2)S成因,并开展了H_(2)S抑制剂优选试验。研究结果表明,H_(2)S抑制剂TS-762室内评价呈现良好的脱硫效果,且TS-762与油田水处理系统使用的化学药剂具有良好的配伍性。试验区块应用结果表明,TS-762能够有效发挥生物竞争排斥作用,区块中采油井产出的H_(2)S浓度显著降低。
To solve the problem of high H_(2)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 H_(2)S in the oilfield,and a H_(2)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 H_(2)S concentration produced by the production wells in the block is significantly reduced.
