摘　　要：汞具有高挥发性、高毒性及腐蚀性,对人身、设备及环境具有重大危害,严重影响了气田开发和利用的安全性,目前已引起了涉汞油气田的高度关注。气田水中不同汞形态主要由难溶性汞(悬浮汞),可溶态汞(单质汞、无机汞、有机汞)组成。气田水中汞形态分析的前处理方法主要有金管富集法、液液萃取法、蒸馏法和膜分离法等。汞形态分析方法主要有气相色谱法、高效液相色谱法、质谱法、原子吸收光谱法及各分析方法之间的联用技术。研究分析气田水中汞的形态,可为气田水选择适当的净化处理技术。同时为气田作业区汞防护措施研究提供依据,做好汞污染的防控。The mercury has high volatility, high toxicity and corrosivity, and it can directly affect the security of gas field development and utilization, and it has a serious harmfulness to the environment and processing equipments, so it has been paid close attention to by the related production units. Different mercury speciation in gas field water is mainly composed of difficult insoluble mercury（suspension mercury）, soluble state mercury（elemental mercury, inorganic mercury and organic mercury）. Pretreatment methods for mercury speciation analysis of gas field water mainly include gold pipe enrichment method, membrane separation method, liquid-liquid extraction method, distillation method, etc. Mercury speciation analysis methods mainly include atomic absorption spectrometry, gas chromatography, high performance liquid chromatography, mass spectrometry and combined technologies of various analysis methods. Studying and analyzing mercury speciation in gas field water are helpful to choose an appropriate purification and treatment technology for gas field water. At the same time, it can also provide a basis for the study of the mercury protection measures against the gas field working area, so as to well prevent and control mercury pollution.
