摘要
The zeolite are widely distributed in volcanic rocks of Santanghu Basin, and the main groups developed in volcanic reservoirs of Carboniferous-Upper Permian strata are Haerjiawu Group,Kalagang Group, Tiaohu Group. Based on the study of the rock composition statistics of the wells in the selected area, the authors found that volcanic rocks were mainly intermediate and basic lava,amygdala developed relatively abundant, the filling holes in almond are typically zeolite-based soluble minerals and this characteristic create the helpful conditions for the post-dissolution. The results have shown that the main reason of laumontite formation are hydrothermal, metasomatic alteration and volcanic materials hydration, and so on.
