摘　　要：油气田烃类的垂向微渗漏造成上覆地层的还原环境,油气田的开采则加剧了还原环境的形成。对新场气田还原环境的形成进行了研究,初步探讨了这种还原环境的形成机制;并从与油气渗漏有关的微生物、气田地表黄铁矿的分析、井水中水溶烃的分析三方面来说明气田地表的还原环境的形成。气田烃类渗漏将对当地生态环境的造成一定影响。Upward micro-seepage of hydrocarbon causes reductive environment in the overlying strata and the oil ＆ gas exploitation intensifies formation of the reductive environment. This paper deals with the formation of reductive environment in Xinchang oil ＆ gas field and discusses the formation mechanism from analysis of micro-organism related to seepage of the oil ＆ gas, pyrite occurring at the ground surface and hydrocarbon dissolved in water of the wells in the oil ＆ gas field. Gas seepage causes a certain ecologic influence on the local area.
