摘要: 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.

关键词: 包裹体, 均一温度, 油气地质, 沉积岩, 塔里木盆地

Abstract: The diagenesis of detrital and carbonate rocks of upper Cretaceous and Miocene in Artashi depression,Tarim Basin was studied.Thin section observation,electron probe analysis and cathodoluminescence method,the parameters of homogenization temperature,pressure,salinity and density were measured respectively from different authigenic minerals in various diagenetic stages.Meanwhile,the paleo geotemperatures were restored and their gradients were also calculated.Based on the measured parameters together with the distributing feature and evolutionary regularity of both salt solution inclusions and organic ones in this area.The oil gas evolution,migration stage and prospective value were preliminarily disscussed.

Key words: inclusion, homogenization temperature, oil-gas geology, sedimentary rock, Tarim Basin
