| 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。

| Abstract: | 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. |

| Keywords: | reductive environment oil and gas microseepage geochemistry Xinchang gas field |
