垦利10—1构造沙河街组发育多套含油砂岩储集体，这些砂岩储层内的成岩现象十分丰富。应用扫描电镜、岩石薄片、粘土矿物及物性资料，对该储层成岩矿物成分、结构和产状进行了分类及特征分析。研究发现：垦利10-1南区沙河街组油层中自生粘土矿物含量高，它们以孔隙充填形式或薄膜包裹颗粒形式堵塞粒间孔隙和喉道，使储层渗透率降低；油层中自生石英加大发育，颗粒表面及粒间孔隙被较完整的石英自形晶面所充填，使储层渗透率降低；油层中碳酸盐胶结一交代现象明显，这种矿物以菱面晶体产状充填粒间孔隙，对油层物性影响较大。而该储层中长石的强烈溶蚀又改善了油层的储集性能，使这一探区具有上亿吨级的储量规模。

Kenli 10-1 Structure of Shahe Street Group developed severa~ sets ot oily sanu rock reservoir, the sandstone reservoir diagenesis and the phenomenon is very rich in. Appli- cation of scanning electron microscope, the rock thin section, clay mineral and physical properties data, the reservoir diagenetic mineral composition, structure and occurrence of the classification and characteristic analysis. Study finds： Kenli 10-1 South Shahe Street forma- tion of authigenic clay minerals content is high, they with pore filling form or film-coated particles form plug intergranular pore and throat, the reservoir permeability decrease; forma- tion of authigenic quartz grain surface and increase development, intergranular pore is more complete quartz automorphic crystal surface by filling, the reservoir permeability reduction; oil reservoir of carbonate cement in replacement phenomenon is obvious, the mineral with rhombohedron crystals produce filling intergranular pore, reservoir properties influence. The reservoir of feldspar dissolution and improve the strong oil reservoir performance, make this one area has reserves of 100 million tons of class.
