摘      要：In order to raise the level of reflection seismology data processing and to test the method of velocity estimation and migration imaging, the geophysical organizations, such as IFP (Institute Francois de Petrole) and SEG/EAGE, have proposed 2D Marmousi model and 3D salt dome model, which have widely used in explorative geophysics. However, those two models are based on the geological background of Europe and the Middle Eastern, which reflects the sedimentary character of marine facies. In order to accelerate our terrestrial facies reservoir geophysics research, to meet the need of our country to method and technique and to make geological model for testing seismic data processing be able to demonstrate the special character of our terrestrial sedimentary facies, the academic committee of reservoir geophysics project, suggested to set up a typical model for China. For realizing this suggestion, Chen Shu Min, Guan Ye Jun, and Fu You Sheng from Daqing oil field proposed 2D geology model, so called China terrestrial facies fault depression model, based on the practice interpretation result given by Wang Pu Jun、 Shan Xian Long from Changchun Science and Technique University, as a testing tool for research of methodology in the reservoir project. Liu Hong and Gao Hong Wei from the Institute of Geology and Geophysics, CAS, completed the tessellation of the proposed terrestrial facies fault depression model and digitalization of velocity model. After that, Dong Liang guo, Wang Hua Zhong from Tongji University carried out the seismic reflection wave numerical simulation by means of self developed simulation software, worked out a 60 fold seismic data on the model for reference in this research area. Terrestrial facies fault depression model show the structural characteristics of Daqing igneous (Fig.1). The length of whole model is 60km, depth 4km; the deep tectonics is very complex, the main characters of tectonics are as followes. 1. Under the action of rise igneous, fault
