塔里木盆地东部,具有下部碳酸盐岩、上部碎屑岩地层层序和古隆起、中坳陷、晚稳定的构造发育史。上元古界—下古生界烃源岩有机质丰度高,油气资源雄厚;生储盖组合配置好,背斜构造和地层圈闭大,大型碳酸盐岩油气藏形成条件优越。北部的群克低凸起(原孔雀河斜坡)和南部的塔东、罗南低凸起,分别是塔北隆起和塔中隆起向东的延伸部分,而且较塔北隆起和塔中隆起构造部位更高,是油气长期运移和聚集的指向。建议加强塔东和群克低凸起寒武系灰岩背斜油气藏和震旦系白云岩地层不整合油气藏的勘探。

The east of the Tarim Basin, which possesses a stratigraphic sequence of carbonate rocks in the lower part and clastic rocks in the upper part, has a tectonic development history of uplifting in the ancient stage, down-warping in the middle and stabilizing in the late. The Upper Proterozoic-Lower Paleozoic source rocks contain high abundance organic matter, and are better oil and gas resources. They have the advantages of forming large carbonate rock oil and gas pools, including good source-reservoir-caprock assemblages, and large anticline structures and stratigraphic traps. The Qunke Low Convex (called the Kongquehe Slope) in the north and the Tadong and the Luonan low convexes in the south, which are the east extension of the Tabei Uplift and the Tazhong Uplift and higher than the Tabei and Tazhong uplifts,are the direction of oil and gas migration. It was suggested that the further survey should be enforced in the Cambrian limestone anticlinal pools and the Sinian dolomite unconformity pools in the Tadong and the Qunke low convexes.
