With the increased proportion of lithologic hydrocarbon reservoirs in China, the exploration objects gradually change from shallow water to deep water area in lacustrine basin, it will break the concept that the deep-water area is a forbidden zone for hydrocarbon exploration .The study of sedimentary facies and sedimentary origin are especially important for China‘s Meso-cenozoic lacustrine basin.The study level on deep-water deposition is low, level especially in deep-water fine-grained sedimentation is in its infancy, and it mostly focused on analysis of the potential of hydrocarbon source rocks in the early stages. This article mainly discusses the developments in aspects of deep-water autochthonous sedimentation, tuff, deep thermal fluid, distal turbidite, radioactive uranium,a research method of example from fine-grained deposits from Yanchang Formation in Ordos Basin. Nanotechnology will be the main research methods in current and the future. Also, this paper discusses the predominance and possibilities of fine grain-size sedimentary rocks in deep water as the hydrocarbon source rock and reservoir of petroleum system.
