溶解作用作为最为重要的建设性成岩作用是石油地质学家和沉积学家多年来长期研究的重要课题之一。西湖凹陷古近系储层砂岩发育有较为普遍的溶解作用,长石是各种类型的骨架颗粒中最为重要的被溶解的组分。本文主要从成岩角度讨论有机酸溶解作用机理以及溶解介质的主要来源。
Dissolution, as one of the most important constructive diagenesis, is one of the most important research topics for petroleum geologists and sedimentologists over the years. The development of sandstones in the Paleogene reservoirs in Xihu sag has a relatively widespread dissolution. Feldspar is the most important dissolved component of various types of framework particles. In this paper, the mechanism of organic acid dissolution and the main sources of dissolution medium are discussed from the diagenetic point of view.
