The study of oil geologic anomalies is a new area of petroleum geology. Using the evidence weight method, we selected tectonic, hydrocarbon abundance of source rock, thickness of source rock, level of reservoir, complexity of reservoir, degree of mineralization of formation water as the evidence layer to evaluate the favorable zones of pool forming in the Lower Paleozoic in the north edge of the Middle and Lower Yangtze areas. Finally, we integrated our results with the petroleum geology of this area and concluded that the North Sichuan basin, the western area of Hubei and the eastern area of Chongqing and parts of the Lower Yangtze are the most profitable areas for exploration in the north edge of the Lower and Middle Yangtze areas. |
