  • 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.
