针对以酸性气田为主的四川地区，研究如何在该地区钻井过程中准确测定钻井液中的H2 S含量，通过何种技术手段去除钻井液中的 H2 S ，以防止其对钻井作业的影响已逐渐成为四川气田勘探开发的一个重要课题。简述了钻井液中 H2 S来源、存在状态及其危害，详细介绍了碘量法测H2 S的方法步骤，并对该方法中试液加入量的影响进行了研究。同时，将其实际运用于四川地区的多口井中，总结出现场碘量法测 H2 S的注意事项，对碘量法测定现场钻井液中的H2 S具有十分重要的意义。

According to the acid gas field of Sichuan area ,an important project of Sichuan gas field exploration and development is that how to determine hydrogen sulfide content accurately in the drilling fluids during the drilling process in the region ,and by w hich means to remove hydro-gen sulfide from drilling fluids so as to prevent its effect on the drilling operation .This paper de-scribes the source ,existing state and harms of hydrogen sulfide in drilling fluids ,introduces a method of measuring hydrogen sulfide by iodometric method ,and studies the influence of the adding amount of test solution .At the same time ,this method has been used in several wells in Sichuan area ,and the attentions of testing hydrogen sulfide by iodometric method have been summed up ,which has very important meanings for the determination of hydrogen sulfide in drilling fluid .
