| 摘 要： | 本文对研究区段上侏罗统砂岩储层的次生孔隙进行以下探讨：①大洼—昌图凹陷砂岩储层次生格架颗粒溶孔和粒间溶蚀扩大孔的形成机制；②张强凹陷砂岩储层次生格架颗粒溶孔和碳酸盐胶结物溶孔的形成机制。在此基础上论述了沉积问断的存在，泥岩中有机质的丰度和干酪根类型是控制次生孔隙发育的主要因素。

| Abstract: | This paper describes the generation mechanism of secondary proosity and its control factors in sandstone hydrocarbon reservoirs of Uppor Jurassic,Tieling-Changtu basin:the gene-ration mechanism of framework grain dissolution pores and enhanced intergranular dissolution pores is related to the telogenetic percolating meteoric water corresponeing with the sedimentary hiatus during the end of Late Jurassic in Dawa-Changtu depression. The generation mechanism of framework grain dlssolution pores and carbonate dlssolution pores is related to the maturation of organic matter in the shale of Zhangqiang depression. It is very imporant to understand the generation mechanism and control factors of dissolu-tion porosity,which allow us to make regional evaluation Of reservoirs. |
