Holographic nondestructive testing of the models similar to geologic structure

n this paper , the method of holographic nondestructive testing is used to analyze qualitatively the deformation characteristics of twenty one types of models.They represent the local geologic structure sections under stress of geologic environment in Sichuan Basin of China. According to these deformation characteristics , the growth position and cracking tendency of the fracture of geologic structures can be predicted. When this method is applied,the tested models generally need to be pressured slightly and the holographic interference fringes due to double-exposure are taken. The appearance of areas in which the interference fringes get locally denser or the curvature of the fringes shows uncontinuity implies the existance of structure fractures. The dimensions of fracture corresponds to the size of the area having densifying fringes and the density of interference fringes is related to the depth of fracture. This gives out some experimental bases for evaluating oil-gas structure and choosing the well-position, the results coincide with the practical gas-field exploration.
