经过多年的注水开发,濮53块储层发生了重大变化。填隙物在注水开发过程中被水冲刷后发生溶蚀、运移,改变了层内部的孔喉网络特征,使其更加复杂化。储层物性的变化体现在孔隙度和渗透率的两极分化严重,好的更好,差的更差。同时长期注入水改造使储层润湿性明显地转化为水湿。 After years of waterflooding, significant changes have taken place in Pu 53 reservoir. During the waterflood development process, the caving material is eroded and transported after being washed by water, which changes the pore-laryngeal network characteristics in the layer and makes it more complicated. Changes in physical properties of the reservoir are reflected in the serious polarization of porosity and permeability, better and worse. At the same time, long-term injection of water into the reservoir wettability significantly transformed into water wet.
