摘要
In this paper, by systematical analysis of more than 300 formation water data from Upper Triassic Xujiahe Formation and Jurassic Formation in the middle area of West Sichuan Depression, the vertical geochemical variation characteristics of formation water and the corresponding water-rock interaction processes recorded by chemical characteristic was discussed preliminarily. Albitization of anorthite in Xujiahe Formation was an important water-rock interaction process, the other diagenetic types occurred in Xujiahe Formation included chloritization, dissolution of carbonate mineral and albite.
