In Wangji area, the target intervals are shallowly buried, and the two groups of fractures in the northeast and northwest direction are cross-cutting. In addition, small faulted blocks are developed and the velocity has large lateral variation, so the small faults are difficult to identify. Aiming at the problems, the authors adopted tomography inversion statics and stretching distortion cut technology, used pre-stack time migration technology, during the velocity model building, and took full account of the structure characteristics and the law of velocity variation. In the research of high-precision 3D seismic imaging, the authors focused on the selection of the key parameters of pre-stack migration. Through the integrated interpretation, a group of new traps in HeⅢ lower segment were obtained.
