EXPLORATION DIRECTION OF LARGE CARBONATE ROCK OIL AND GAS POOLS IN THE EAST OF THE TARIM BASIN

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.
