四川盆地加里东古隆起的形成演化具有长期性和复杂性 ,使得古隆起震旦系的天然气成藏有早有晚。早期成藏主要发生在印支期 ;晚期成藏主要发生在喜山期。每期成藏可以划分出 3种不同的成藏类型 :即高捕集高阻抗、高捕集低阻抗及低捕集。天然气藏的主要控制因素为“两高一强一关联” ,即较高的封存能力、较高的构造部位、较强的构造形变 ,晚期形成的圈闭与古油气藏具有密切关联。
The formation and evolution of the Gallongonggou uplift in the Sichuan Basin has the long-term and complex nature that the natural gas accumulation in the Sinian uplift from the Gurion has been delayed. Early accumulation occurred mainly in Indosinian; late accumulation occurred mainly in Himalayan period. Each reservoir can be divided into three different reservoir types: high capture high impedance, high capture low impedance and low capture. The main controlling factors of natural gas reservoirs are “two highs and one strong one correlation”, that is, higher sealing capacity, higher tectonic positions and stronger tectonic deformation. Late traps are closely related to paleo-oil and gas reservoirs.
