RELATIONSHIP BETWEEN NEOTECTONIC MOVEMENT AND STRUCTURAL EVOLUTION AND GAS POOLS FORMATION OF SICHUAN BASIN

The neotectonic movement in East China controls the formation of the Tertiary rifting basins that are rich in oil gas. It reforms structural geology for generating the Paleozoic Mesozoic oil gas pools in the Upper Yangtze Platform and Qingzang Plateau. A lot of oil gas beds are disappearing. The uplifting of Qingzang Plateau constructs the center of the neotectonic movement of China, controlling the evolution of fault folding structures and the distribution of marine carbonate gas pools. The existent oil gas pools in the anticlines with higher development are damaged, and blind anticlines with low medium development are rich in natural gas. Geological structural conditions for the oil gas formation and preservation in Sichuan Basin can be conducted to find oil gas pools in the Upper Yangtze Platform and Qingzang Plateau.
