Abstract

Abstract: The genesis of hydrogen sulfide is of great significance for understanding the natural gas accumulation in carbonate reservoirs. In this study, core samples are taken from Well Tao112 in mid-eastern Ordos Basin. Through the systematic sample collection, thin section polish, petrography observation of fluid inclusions, cathode-luminescence analysis, microthermometry and laser Raman spectroscopy test of fluid inclusions, this paper analyzes the genetic type and forming mechanism of hydrogen sulfide, and explores the characteristics of natural gas accumulation at the middle and lower assemblages of Majiagou Formation. The results show that the original abundance of hydrogen sulfide of Majiagou Formation in Well Tao112 is significantly greater than 5%, and its formation temperature is 160-220℃, so the hydrogen sulfide is the product of thermochemical sulfate reduction (TSR). In the TSR, the gypsum-salt rock section in Majiagou Formation is the main source of sulfate minerals. The natural gas from the Upper Paleozoic coal-measure source rock and the marine source rock of Ordovician Majiagou Formation may provide hydrocarbon sources for hydrogen sulfide generation. The high reaction temperature and formation pressure difference ensure the occurrence and continuation of TSR.

Key words: hydrogen sulfide, fluid inclusion, natural gas accumulation, Ordovician, Majiagou Formation, Ordos Basin

摘要： 硫化氢成因对认识碳酸盐岩型天然气的成藏问题具有重要意义。以鄂尔多斯盆地中东部地区Tao112井马家沟组岩心样品为研究对象，通过系统采样、薄片制备、流体包裹体岩相学观察、阴极发光分析、显微测温和流体包裹体激光拉曼光谱测试，分析了研究区硫化氢的成因类型和形成机制，探讨了马家沟组中、下组合天然气的成藏特征。结果表明，Tao112井马家沟组中硫化氢的原始丰度明显大于5%，形成温度在160~220℃，为热化学硫酸盐还原（TSR）反应成因。在马家沟组发生的TSR反应中，马家沟组中的膏盐岩段是最主要的硫酸盐矿物来源；上古生界煤系烃源岩和奥陶系马家沟组海相烃源岩生成的天然气可能提供了生成硫化氢所需的烃类供应条件；较高的反应温度和地层压力差保证了TSR反应的发生和持续。
