| 摘 要： | 硫化氢是石油伴生气中的有害成分之一。目前有关油气田伴生硫化氢的成因,存在着生物成因(SBR)、热化学成因(TSR)两种不同观点。本文从安塞油田地质环境条件下的烃类与岩心中的金属硫酸盐反应热力学分析,探讨了石油生产过程中硫化氢产生的可能机理,并结合地层水质分析及岩心分析结果,发现在安塞油田地质条件下,井下缺少微生物活动的必要条件,从而排除了BSR成因的可能性,论证了TSR成因应为安塞油田硫化氢产生的主要原因。

| Abstract: | Hydrogen sulfide is a kind of toxic gas which widely coexisted in oil field gas.The argument of hydrogen sulfide causation in oil field is mainly being concluded as Sulfur Bacteria Reduction(SBR) and Thermal Sulfate Reduction(TSR).The paper estimated the possibilities of hydrogen sulfide production from reaction of hydrocarbons and alkaline earth metal sulfates by thermodynamics and concluded that the hydrogen sulfide can be produced at the condition of typical temperature and pressure of oil well undergrou... |
