Abstract: The North Yellow Sea basin on the Sino-Korean plateau is a Mesozoic-Cenozoic fault basin. The Mesozoic sandstone reservoirs featuring low permeability nature are proved to be the main exploration targets by drilling, and fractures inside are found to be the main reservoir space of the discovered oil pools. Based on the 3D seismic, core observation and imaging well logging data, this paper, by means of the latest FracPM curvature analysis with the characteristic of global optimization algorithm, combined with the ant?tracking method， achieves the high precision imaging of fractures. At the levels of big and small scale, the fracture growth level and distribution of the exploration targets are predicted, and good practical effects are obtained. The predicted fractured layers are proved by drilling with great hydrocarbon potentials
