随着勘探和研究的深入，石膏盐岩系列作为良好的盖层引起了人们的广泛关注。膏盐岩系在油气运移、保存和圈闭过程中发挥了重要作用。近年来，中国盆地在鄂尔多斯盆地东部、塔里木盆地中部、四川盆地西部的膏盐岩系海相油气勘探不断取得重大突破，使高演化、低丰度的膏盐岩系列成为可能。在膏盐岩系储盖组合研究进展的基础上，从生烃环境和生烃机制等方面对膏盐岩系烃源岩的发育和生烃潜力进行了较深入的研究。结果表明，中国地区的膏盐岩系列包括高演化、低有机碳的膏盐岩系列，是良好的生油岩。这一认识突破了以往认为低TOC膏盐岩系不能作为有效烃源的传统观点。了解生烃机理的关键是在高演化、低TOC的膏盐岩系中发育了丰富优质的生烃物质、地质史上大量的生烃转化和以羧酸盐形式存在的生烃物质。
With further exploration and research, the gypsum-salts rock series as good caprocks attracted a lot of attention. The gypsum-salt rock series played an important role during migration, preservation and trapping of hydrocarbons. Recently, major breakthroughs have been continuously made in marine petroleum exploration of gypsum-salt rock series in the eastern Ordos Basin, the central Tarim Basin and the western Sichuan Basin in China, and the high-evolution and low-abundance gypsum-salt rock series as hydrocarbon source rocks become possible. Besides research advances in the reservoir–caprock assemblage of gypsum-salt rock series, development and hydrocarbon-generation potential of source rocks in the gypsum-salt rock series were well studied in terms of source-rock development environment and hydrocarbon generation mechanism. Results showed that the gypsum-salt rock series, including high-evolution and low-TOC gypsum-salt rock series in China, could be regarded as good source rocks. This understanding was a breakthrough to previous traditional viewpoint that low-TOC gypsum-salt rock series could not act as effective hydrocarbon sources. The key to understand hydrocarbon-generation mechanism was that abundant and high-quality hydrocarbon-generation materials, large amount of hydrocarbon generation and conversion in geological history, and hydrocarbon-generation materials occurred in the form of carboxylates, were developed in the high-evolution and low-TOC gypsum-salt rock series.
