运用镜下岩石组构鉴定、电子探针分析、阴极发光技术等手段，在对塔西南叶城凹陷坳陷上白垩统至中新统碎屑岩和碳酸岩盐成岩作用研究的基础上，分别测试了各成岩阶段不同期次自生矿物的均一温度、盐度、密度等参数。恢复了本区的古地温，并计算了古地温梯度。结合本区两类包裹体（盐水溶液包裹体和有机包裹体）的分布和演化规律，对本区油气演化、运移阶段及远景预测作了初步探讨
Based on the study of the rock structure identification, electron probe analysis and cathodoluminescence, the study on the diagenesis of the Upper Cretaceous to Middle Neolithic clastic rocks and carbonatite rocks in the depression of the Yecheng Depression in the southwestern part of Tarim Basin, respectively, The parameters such as homogenization temperature, salinity and density of authigenic minerals in different stages of each diagenetic stage were obtained. Restored the ancient geothermal temperature in this area, and calculated the ancient geothermal gradient. Combined with the distribution and evolution of two types of inclusions (saline solution inclusions and organic inclusions) in this area, the evolution, migration and long-term prediction of oil and gas in this area are discussed
