As pH value varied in the course of diagenesis,reservoirs experienced one to three cementations or dissolution generations.Lots of secondary dissolution pores developed in the late diagenetic stage,because of the acidic mediums in the process of generation and migration of oil and gas. The anhydrites deposited in the dissolved pores resulted in the heterogeneity of secondary pores.

储层在成岩过程中受地层水pH值变化的影响，经历1~3个世代的胶结或溶蚀作用，其中在晚成岩期油气生成和运移过程中形成的酸性成岩环境对早成岩期生成的碳酸盐岩胶结物和储层中的长石矿物溶蚀，因而产生了大量的次生溶孔，但随后在溶孔中沉淀了不等量的硬石膏，导致了次生孔隙的非均质性。
