摘　　要：以东部某油田的集输站、注水站、油井等区域作业人员及周边居民反映的异味气体为研究对象,通过系统采样,开展了气体组成剖析及重要组分的定量测定。确定了油田异(臭)味气体的主要成分,其中烃类主要包括丙烷、异丁烷、正丁烷和异戊烷,可能引起恶臭等异味的物质主要为含硫化合物。进一步检测表明,含硫化合物主要包括硫化氢、甲硫醇、乙硫醇、甲硫醚,并基于恶臭当量计算,确证了其异味主要来源为硫化氢。Taking the odorous gases reflected by operators and residents in gathering and transporting stations,water injection stations and oil wells of an Eastern oilfield as research objects,gas composition analysis and quantitative determination of important components were carried out through systematic sampling and analysis. The main components of oilfield odor gases were determined,among which hydrocarbons mainly include propane,isobutane,n-butane and isopentane,and substances that may cause odorous gases are mainly sulfides. Further detection showed that sulfides mainly included hydrogen sulfide,methyl mercaptan,ethyl mercaptan and methyl sulfide. Based on odor equivalent calculation,hydrogen sulfide was confirmed as the main source of odor.
