The thesis also discussed the synthetic influence of above factors on dynamic diagenesis in detail and graded dynamic diagenesis into three types, which were respectively thermally dynamic diagenesis, tectonically dynamic diagenesis and hydrokinetic diagenesis, and then the types of diagenesis controlled by dynamic factors had been studied: 1 thermally dynamic diagenesis, clarified the ration relationship by the conception of the thermally evolving track and the thermally maturity, 2 tectonically dynamic diagenesis, changed the porosity of reservoir mainly by tectonically movement;3 . hydrokinetic diagenesis, changed the physical and chemical properties resist-press intensity of the rock by the participating of liquid.

在研究以上控制因素的基础上，将成岩动力作用分为热动力、构造动力、流体动力成岩作用三种类型：1、热动力成岩作用，运用热演化轨迹和热成熟度的概念研究与成岩作用之间的定量关系，砂岩孔隙度随热成熟度增加而呈指数减小；2、构造动力成岩作用，盆地构造变形可以使砂岩的孔隙体积在相对短的时间内产生明显的变化，构造滑脱推覆作用比水平侧向挤压作用压实减孔量小，可保留更多的孔隙度；3、流体动力成岩作用，化学成岩反应是在流体参与下完成的，它改变了岩石的物理化学性质，改变了岩石的抗压强度。
