| 摘 要： | 为探讨硫化氢生成的热化学还原反应条件,从鄂尔多斯盆地选取石膏、地层水和天然气样开展了模拟实验。实验在密闭的温压釜中进行,多组实验结果表明:热化学还原反应除需要石膏、烃类外,还必须有地层水参与才能进行;硫化氢生成量与反应温度、时间正相关;硫化氢生成过程存在34S同位素分馏,且温度越高分馏幅度越小。研究说明,在石膏、烃类气体存在的前提下,高温、密闭还原、有地层水是该反应进行的必要条件。把握这5个条件是建立区域硫化氢生成模型的基础。

| Abstract: | In order to explore the condition of thermochemical sulfate reduction on sulfureted hydrogen,selected samples of gypsum,formation water and natural gas in Ordos Basin and maked experiment in airtight kettle.The result of the experiments indicated,the thermochemical sulfate reduction need add formation water,besides gypsum and hydrocarbon.Amount of a sulfureted hydrogen produced and corresponsive temperature or time are relation of direct proportion.During experiment with fractionation of 34S isotope,and fractional strength be reduced with rise temperature.The study showed,besides gypsum and hydrocarbon,high temperature,airtight reductive environment and formation water are necessary condition of thermochemical sulfate reduction.Above five conditions are foundation of found regional model of sulfureted hydrogen. |
