Abstract: With the petroleum exploration and development of many oilproducing countries or areas in the world becoming increasingly mature, the problem of reservoir geology has become one of the main bottleneck problems of restricting petroleum exploration and development in petroleum industry. In order to improve exploration success ratio and development EOR and to further realize the purpose of “increasing reserves and production”, to carry out comprehensively the precise prediction for the spatial distribution of multiparameter of a sedimentary reservoir and the research on characterization methods and technologies have become the indispensable content in the current work of petroleum geology. The principally important is that they all can't depart from the kernel foundation of reservoir sedimentology. Started from 1960s, reservoir sedimentology has a development course of over 40 years. Based on the summery of the research progress both in China and abroad, this paper mainly has applied a view of historical materialism to expatiate the formation background of this subject, the demands of petroleum industry, the interpenetration of multidiscipline, the formation and development trend of this subject's specialization and research approaches. Meanwhile, current some research hot points of clastic reservoir sedimentology have been summarized and discussed, such as research methods of modern sedimentation and outcrop, application of geophysical method, the mapping method of sedimentary facies by multiparameter, application of sequence stratigraphy, the genesis of sedimentary reservoir in deep water, the formation and application of seismic sedimentology, depositional filling models of nonmarine basin, and reservoir diagenesis, etc. And then, some suggestions have been put forward on important problems to deepen the research on this subject.
