摘　　要：利用阴极发光、扫描电镜、偏光和荧光等测试技术,通过对胜利油区不同勘探区带深层砂砾岩体取心资料的系统分析,阐述了不同洼陷、不同层系、不同深度砂砾岩体成岩演化特征的差异和孔隙发育规律。研究发现,在东营、埕南和车镇地区,砂砾岩体的储集空间类型、分布和成因机制存在明显异同。结合对储层沉积物源、构造发育和流体活动特征的研究,确定了影响储层发育的3大主控因素,即物质组成中形成的刚性岩石构架、成岩层序界面的疏导作用和3类不同性质的流体(酸性、碱性、含烃流体)对储层的后期改造作用。Test methods of cathodeluminescence,scanning electron microscope,polarized light and fluorescent light were applied to systematic analysison core data of deep buried glutenite reservoirs in various exploration areas of Shengli Oilfield. Diagenesis difference and evolution rule ofinterstitial space in different sags,diverse parasequence sets and different depth of glutenite reservoirs were expounded. Both difference andhomology exit on types,distribution and genetic mechanism of reservoir space in Dongying,Chengnan and Chezhen glutenite reservoirs.Three factors controlling evolution of reservoir were analyzed through the research of sedimentary provenance,stricture development and fluid activity features of the reservoirs. They are rigidity matter of rock truss,leading process of diagenetic sequence interface and rebuilding ofthree different properties fluid (acidic,alkaline and hydrocarbon-bearing liquid) to reservoir.
