Abstract: 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 resources 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 obtained 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 discovering 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 hydrocarbon 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 sedimentology will provide new opportunity for energy sedimentology.
