目的：防止钻井过程中出现的硫化氢对人身安全和钻具造成危害。方法：分析氢脆破坏机理和处理硫化氢的化学原理。结果：提出了处理硫化氢的关键技术，并结合塔中162井的实钻经验，总结出了钻井过程中对硫化氢的几点认识。结论：提高泥浆pH值、加入除硫剂及提高泥浆密度等措施是钻井过程中处理硫化氢的关键技术，从而有利于富含硫化氢的灰岩、白云岩等裂缝性油气藏的钻井生产。
Purpose: To prevent the occurrence of hydrogen sulfide in the drilling process to personal safety and drill hazards. Methods: The chemical mechanism of hydrogen embrittlement failure and chemical treatment of hydrogen sulfide were analyzed. Results: The key technology of hydrogen sulphide treatment was put forward. Combined with the actual drill experience of well Tazhong 162, several understandings of hydrogen sulphide during drilling were summarized. Conclusion: The measures of increasing the pH value of mud, adding desulphurizing agent and increasing the density of mud are the key technologies to treat hydrogen sulfide in drilling process, which is benefit to the drilling production of fractured reservoirs such as limestone and dolomite with hydrogen sulfide.
