Liu Jun, Xu Youping, Liu Xiaohong.Application of 3D prestack depth migration integrated processing technique in the study of the Inner Mengdu buried hill reservoir in Jizhong Oilfield. Petroleum Geophysical Prospecting, 2 0 0 3 38 (3): 2 37 ~ 2 4 1 The structure of the South Mengzangshan fault in Jizhong Oilfield is complicated. The seismic imaging accuracy of the time-shift method used in the past is not high. In this paper, the 3D prestack depth migration method is used to reprocess the seismic data of Nanmeng buried hill. The processing flow includes: conventional 3D processing, establishment of time domain geological model, fine velocity analysis, establishment of velocity field, final migration imaging and modification. According to the reprocessed prestack depth migration data, the structures of Fujun Mountain, Changlong Mountain and Wumishan have been implemented and high-yield commercial oil flow has been obtained in the sandstone reservoir of Changlongshan Formation.
