【摘要】：沉积学发展与石油、天然气、煤炭、砂岩型铀矿等矿产资源工业化开采紧密相关,能源沉积学作为沉积学的一个重要应用分支学科,在资源勘探发现中的地位越来越重要,已经成为有效发现资源、降低成本的重要途径。近年来,能源沉积学在技术方法上建立了遥感、雷达、地震、纳米CT等六个级别尺度研究方法,为沉积储层学科发展提供支撑。在理论认识上取得了五方面重要进展:1)建立了克拉通台地沉积储层新模式,为古老含油气系统提供理论指导;2)建立海陆相细粒沉积成因模式,揭示富有机质页岩分布规律,为烃源岩评价与非常规油气勘探开发提供重要理论依据;3)发现非常规致密储集层微纳米级孔喉系统,指导致密油气和页岩油气储层评价;4)研究含煤沉积体系和聚煤作用,指导煤炭资源评价;5)揭示砂岩型铀矿富集机理,指导铀矿资源评价与开采。展望能源沉积学发展,源—渠—汇沉积体系、海陆相细粒沉积学、古老小克拉通碳酸盐岩沉积学等将成为能源沉积学的重要内容;储层非均质性、非常规储层全面表征与深部储层极限将是储层沉积学发展的热点,砂岩型铀矿、煤系等沉积系统是固体矿产沉积研究的重点领域;气、液、固不同能源矿藏空间有序沉积与共生规律研究是资源勘探重点方向;大数据与沉积学方法创新将为能源沉积学发展提供新机遇。
[Abstract]:The development of sedimentology is closely related to the industrial exploitation of mineral resources such as oil, natural gas, coal and sandstone-type uranium deposits. As an important applied branch of sedimentology, energy sedimentology plays an increasingly important role in resource exploration and discovery. It has become an important way to find resources and reduce cost effectively. In recent years, energy sedimentology has established six scale research methods, such as remote sensing, radar, earthquake, nano-CT and so on, which provide support for the development of sedimentary reservoir. A new model of craton platform sedimentary reservoir has been established, which provides theoretical guidance for ancient oil-bearing systems. (2) A genetic model of marine and continental fine grain deposition is established, and the distribution law of organic matter rich shale is revealed. This paper provides an important theoretical basis for source rock evaluation and unconventional oil and gas exploration and development, and finds out the micro-nano pore throat system of unconventional dense reservoir, which can guide the evaluation of tight oil and gas and shale oil and gas reservoirs. (4) to study the coal-bearing sedimentary system and coal accumulation. (5) to reveal the enrichment mechanism of sandstone-type uranium deposits, and to guide the evaluation and mining of uranium resources. The development of energy sedimentology, source-channel-sink sedimentary system, marine and continental fine grain sedimentology, ancient small craton carbonate sedimentology and so on will become important contents of energy sedimentology, reservoir heterogeneity, etc. The comprehensive characterization of unconventional reservoirs and the limit of deep reservoirs will be the hot spots of reservoir sedimentology. The sedimentary systems of sandstone-type uranium deposits and coal measures are the key areas in the study of solid mineral deposits. The research on spatial orderly deposition and symbiosis of solid mineral deposits with different energy sources is the key direction of resource exploration, and the innovation of big data and sedimentology methods will provide new opportunities for the development of energy sedimentology.
