Cross-well seismic physical models and their application

The cost of data acquisition of cross-well seismic is very high, and the general research method mostly focuses on mathematic and physical simulation. The development of physical simulation is laggard relatively. For the particularity of cross-well seismic, a series of researches on solid medium model and integrative laboratorial model were presented to research the physical model of cross-well seismic. The research method and content, data acquisition system, manufactural model, data acquisition, quality control of physical model were discussed. Factors affecting model making and quality control of data acquisition were investigated, and the corresponding measures to insure the quality of model were brought out. The results indicate that the factors affecting the quality of physical model include manufacture die, homogeneity of material as well as the positions of abnormal body and micro structures. The quality could be insured by choosing different materials and techniques according to different aims. Survey system, seismic source, receiver and transducer are the important factors for data acquisition quality. Design of an effective survey system, choice of data acquisition method and equipping excellent seismic source, receiver and transducer for the physical model are the essential qualifications.
