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。
Based on the systematic analysis of the coring data of deep glutenite bodies in different exploration zones in Shengli Oilfield, the paper uses the techniques of cathodoluminescence, scanning electron microscopy, polarization and fluorescence to describe the diagenesis of sandstone conglomerates in different sags, strata and depths Differences in evolutionary characteristics and pore development. The study found that in Dongying, Taonan and Chezhen, there are obvious similarities and differences in the types, distributions and genesis mechanisms of glutenite bodies. Based on the research on reservoir sedimentary source, tectonic development and fluid activity, three main controlling factors affecting the reservoir development are identified, namely the rigid rock framework formed in the material composition, the dedication of the diagenetic sequence interface and the three main types Different types of fluids (acidic, alkaline, hydrocarbon-containing fluids) later remodeling the reservoir.
