为了研究和验证砂岩次生孔隙的形成过程和识别标志,我们进行了砂岩的酸溶模拟实验工作。本文主要说明在酸溶过程中砂岩的矿物成分,孔隙度、渗透率和孔隙结构的变化以及在酸溶铸体薄片中出现的各种溶蚀现象。并据此,对砂岩次生孔隙的形成过程和形成条件进行了阐述。
The acidolysis simulations of sandstone are made to study the evolution and recognition of the secondary porosity of sandstone. The paper mainly discussed about various changes of mineral composition, porosity, permeability and pore texture during acidolysis of sandstone, as well as various dissolutions observed on the thin sections of acidolysis casts. Based on what mentioned above, the evolutional process and the conditions of secondary porosity in sandstone are described in this paper.
