英文摘要This paper applies the Schoenberg fracture media model theory to numerical simulation of elastic wave field in HTI (LSD) media. By means of the numerical simulation we revealed the wave field characteristics of the fracture parameter normal weakness E(N) and shear weakness E(T) (two dimensionless parameters). The results of the wave field simulation indicate that the parameter E(N) has an effect on the fast wave and the parameter E(T) has an effect on the slow wave. E(N) is very sensitive to fluid in fracture, and E(T) is sensitive to elastic characteristics of fracture's own. The conclusion has an important sense for the application of the Schoenberg fracture media model theory in the field of fracture prediction and fluid detection in fractures. The physics meaning of the normal weakness E(N) and the shear weakness E(T) are more definitude than the Thomsen parameters (epsilon, gamma, delta).
