摘要

近地表碳酸盐化和浅埋藏水化水解

使火山砂岩在压实前固结

其中的粒间孔隙被以蒙脱石为主的自生粘土矿物充填或分割。决定孔隙水性质和形成自生粘土矿物及沸石等离子

来自火山砂岩本身。火山砂岩的典型成岩反应是水化水解和脱水反应

决定了孔隙水的性质、成岩矿物组合和储层的物性。

Abstract

The volcanic sandstone had been cemented by calcitization near the ground and by shallow buried hydration-hydrolysis

the intergranular pores of which were filled and separated by authigenic clay minerals.The typical diagenetic reactions of the volcanic sandstone were hydration-hydrolysis and dehydration which decided the property of pore water

the assemblage of diagenetic minerals and the physical property of the reservoir bed.
