辽河清水洼陷东营组高分辨率层序格架下沉积演化特征及有利区带预测
The measured porosity data and the observations of thin sections and blue epoxy resinimpregnated thin sections show that the diagenesis in the Qingshui sag can be divided into two stages and five substages.
根据岩心实测孔隙度、薄片观察、铸体薄片和扫描电镜等实际资料,将辽河盆地西部凹陷清水洼陷新生界成岩作用划分为早成岩阶段和中成岩阶段2个阶段,其中包括5个亚期,指出该洼陷新生界纵向上发育3个异常高孔带,这种异常高空带的形成与大气降水淋滤作用和有机酸对储层的溶蚀作用有关。
