摘要
通过观察岩心 ,鉴定普通和铸体薄片 ,利用扫描电镜、阴极发光、X -衍射、油层物性等分析测试手段 ,研究松辽盆地东南隆起区上侏罗统储层孔隙发育特征 ,认为该区深部构造层物性偏差 ,特别是火石岭组和沙河子组 ;但各断陷普遍发育 2～ 4个次生孔隙发育带 ,是主要的油气储集空间。成岩作用、岩石成分。
It is studied that the growth characteristics of pores in petroclastic rocks of Upper Jurassic in the southeast rise in Songliao Basin through observing cores and thin sections, using scanning electron microscope, cathodoluminescence, X diffraction and reservoir properties analysis. It is indicated that reservoirs in this area had pool porosity and permeability generally, but there were 2 to 4 secondary pore growth zones in each sag, which were the main reservoir spaces. The diagenesis, rock's compositions, sedimentary micro facies and scale of sand bodies are the main influencing factors for the pores' growth.
