中国能源沉积学研究进展与发展战略思考

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。

Research Progress and Development Strategic Thinking on Energy Sedimen-tology

The development of sedimentology depends on industrial exploration of mineral resources such as oil,gas, coal,sandstone type uranium deposit. Energy Sedimentology which becomes an important way for discovering re-sources and reducing cost is more and more important for resources exploration. Recently,the development of oil and gas sedimentary reservoir is supported by Energy Sedimentology,which ob-tained six significance progresses,established six grade measures such as remote sensing,seism and Nano-CT.Energy Sedimentology established new model of craton platform sedimentary reservoir and provided theoretical direction for global ancient hydrocarbon-bearing system. Genetic models of marine and continental facies fine-grained sedimentation were established,regularities of distribution of organic-rich shale were revealed,and important theoretical foundations of source rock evaluation and unconventional oil & gas exploration were provided by energy sedimentology. And dis-covering micro-nanoscale pore throat system of unconventional tight reservoir, guiding assessment of shale and tight reservoirs, studying coal-bearing stratum and guiding evaluation, revealing uranium mine gathering mechanism in sandstone and guiding evaluation,all these achievements can rely on energy sedimentology. Source-to-Sink Approach,marine and continental fine-grained sedimentology and ancient small craton carbonate sedimentology will become significant contents in the development of energy sedimentology. Reservoir heterogeneity, characterization of unconventional reservoir and limit of deep-reservoir will be a hotspot in the development of hydro-carbon sedimentology. Sequential deposition and mutualism regular research of different energy storage space, like gas,liquid and solid,are the key direction of resource exploration. Big data and technique innovation of sedimentolo-gy will provide new opportunity for energy sedimentology.
