采用最小平方共轭梯度法进行速度层析反演，得到井间反射波成像的速度模型，利用VSPCDP成像与克希霍夫偏移相结合的方法对井间地震上行反射波进行精细成像。

The measured porosity data and the observations of thin sections and blue epoxy resin-impregnated thin sections show that the diagenesis in the Qingshui sag can be divided into two stages and five substages. There exist three abnormally high porosity zones vertically in the Cenozoic reservoirs in the Qingshui sag, Liaohe Depression, whose genesis is related to the eluviation of precipitation and the dissolution of organic acid.

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。
