The Initial Interpretation for the Geological Structure and Its Impact on Oil and Gas in the Northeast Margin of the Mid-Yangtze
The widely distributed Mesozoic marine phase carbonate rocks in southern China hold a huge oil and gas exploration prospect. We collected 1:500 000 regional gravity and aeromagnetic, magnetotelluric and deep seismic sounding profiles in the northeast margin of the Mid-Yangtze. By processing the regional gravity and magnetic data and interpreting the gravity and deep seismic sounding data 2.5D interactive inversion, we studied the geological structure there and analyzed the impact of continent-continent collision between the Yangtze and the North China blocks on oil and gas accumulation and preservation. Then we conclude: the Yangtze block which was between Xiangguang and Jiangnan fault, was the largest preservation scope unit for Paleozoic oil and gas in southern China; the foreland basin of the East Qinling Jianghan basin hinterland and its buried inverse-dive tectonic belt, Xuefeng Mountain costa, and Chuanxiangqian inverse-dive high uplift anticline belt were the best preservation units.
