Abstract

Abstract: The composition analysis of natural gases in eight giant carbonate gas fields discovered in China shows that hydrogen sulfide natural gases are mainly distributed in the Triassic and also can be extensively discovered in the Permian,Carboniferous,Ordovician,Cambrian and Sinian systems. It is concluded that sulfate is deposited broadly among the high-content hydrogen sulfide reservoirs and corresponding stratum. The sulfate is one of the key factors for controlling the percentage of hydrogen sulfide in natural gas reservoirs besides temperature and buried history of gas reservoirs. The origin of hydrogen sulfide in the carbonate gas fields mainly depends on reduction of sulfate and cracking of hydrocarbon.

Key words: carbonate rock, gas field, hydrogen sulfide, sulfate rock, gas reservoir

摘要： 具有工业价值的硫化氢气藏可为硫磺产品提供重要资源。对中国目前发现的8个碳酸盐岩大气田中硫化氢气体的含量特征分析表明,含硫化氢气藏主要分布在三叠系,在二叠系、石炭系、奥陶系、寒武系和震旦系也有不同程度的分布。硫化氢含量较高的气田和层位普遍发育硫酸盐岩,这是控制天然气藏硫化氢含量的关键因素,温度和时间也是重要的影响因素。中国碳酸盐岩大气田中的硫化氢是由硫酸盐还原和烃类裂解生成的。
