摘　　要：针对研究区油气勘探程度较低的现状,从岩石学特征、储层特征研究入手,在成岩作用和成岩序列分析的基础上,将成岩作用类型分为两类,分别对泰一段上、下亚段定量分析了储层孔隙演化特征,并建立了孔隙演化模式,深化了储层形成过程及影响因素的认识。研究认为,孔隙演化特征主要受沉积环境、物源及物源区母岩性质、成岩作用、构造作用等因素的共同控制。In consideration of the poor hydrocarbon exploration of the study area,the authors firstly studied the petrologic characteristics and reservoir characteristics,and divided diagenesis into two types on the basis of an analysis of diagenesis and diagenetic sequence, and then conducted the quantitative analysis of the Eltl ~ and Eatl T separately,which developed the porosity evolution model and deepened the understanding of the reservoir formation procedure as well as the influencing factors. The result shows that the porosity evolution features were controlled jointly by the sedimentary environment, material source,parent rock properties of the provenance, diagenesis, and tectonic process.
