Abstract: In the 21st century, geodynamics is developing from qualitative analyses to quantitative analyses. Due to its irreversible characteristic, the geological process is difficult to restore, especially for the recovery of geological parameters' evolution in micro scale, now it has become an important scientific problem in geology. Thereby, the concept of "stratigraphic porodynamics" is proposed, which takes microscopic porous media as research subject and mechanic properties of clastic porous media, evolution laws of pore, dynamic causes of pore fluid and its porous flow characteristics in the buried process of sedimentary basins as research contents. It is not only a new discipline which combines diagenetic dynamics and pore fluid dynamics, but also an important component of basin dynamics, which includes progresses of basic theories and applied researches. Furthermore, advancements of basic theories contain six aspects:(1) static balance principle of formation pore,(2) mechanism of sandstone's porosity evolution and quantitative models in the process of burial and diagenesis,(3) characteristics of mudstone compaction and quantitative models of its porosity evolution,(4) theoretical relationship between pore fluid temperature and pressure underground,(5) impacts on pore fluid pressure caused by structural additional stress,and (6) the relationship between the degree of mudstone compaction and thermal evolution of organic matter. Similarly, progresses of applied researches also include six fields:(1) divisions of geotemperature-formation pressure models and explanations of dynamics of oil distribution,(2) improvements on models of formation pressure prediction,(3) determination of critical properties of reservoir and establishment of its dynamic evaluation system,(4) simulation of evolutionary process of fluid pressure,(5) researches on numerical simulation of sandstone oil charging and physical simulation tests,and (6) analyses on dynamic pool-forming process of tight sandstone hydrocarbon reservoirs. All in all, dynamics of stratigraphic porosity integrates the evolution of porosity causes and fluid dynamics as a whole, which is one of the representative disciplines that symbolize geodynamics researches begin to develop in microscale direction in recent 20 years. Most importantly, it is a corollary of quantitative development of researches on mechanism of sedimentary mineral's formation and distribution. In this paper, based on main contents of stratigraphic porodynamics, eight significant research findings are summarized and we expand geological researches from macroscale to microscale, aiming at solving problems of pore parameters' evolution laws in the buried process and updating skills in the application of exploration and exploitation.
