溶蚀孔隙，又称溶孔，是碳酸盐矿物或伴生的其他易溶矿物被地下水、地表水溶解后形成的孔隙。 溶蚀孔隙指沉积过程及成岩后由于溶解作用所形成的孔隙。地下水的溶解作用往往在沉积过程中就已开始进行，并延续到成岩作用结束。
储层孔隙类型以原生粒间孔隙和次生溶蚀孔隙为主。
The major type of pores of the reservoir were primary pores and the secondary pores.
储集空间主要为次生裂缝和各种溶蚀孔隙，其次为基质孔隙。
Reservoir space is mainly secondary fractures and all types of corroded pores, and secondarily matrix pores.
破裂作用可以提高砂岩的储渗能力，同时也有利于砂岩中溶蚀孔隙的形成。
Fracturing has resulted in an increase in sandstone porosity and permeability and enhanced the development of secondary pores.
