摘要
针对重庆川东北天然气矿钻井作业出现的硫化氢气体中毒故事,该文在介绍硫化氢性质、分布、形成及危害的基础上,具体阐述了井场检测硫化氢气体的几种方法——标准碘量法、快速测定管法、醋酸铅试纸法、硫化氢气报警法和综合判断法;探讨了硫化氢地区钻、录井的安全防范与处理措施;介绍了硫化氢中毒途径、预防措施和现场急救方法。对于指导含硫化氢地区钻井、录井安全作业具有重要作用。
In view of H_2S gas poisoning accident happened during natural gas drilling operation in Chongqi, the paper described some methods of wellsite detecting H_2S gas:standard iodine measurement, fast detecting tube, acetic acid lead test paper, H_2S gas alarm and multiple judging methods on the basis of introducing H_2S gas properties, distribution, forming and harmfulness. The author discussed the safety protection and processing measures during drilling and mud logging in H_2S gas areas and introduced H_2S gas poisoning way, precautions and wellsite emergency treatment methods. The paper has an important guiding action on drilling and mud logging operation in H_2S gas areas.
