This paper introduced the Liner slip deformation (LSD) fracture media model theory, and this theory is applied into the two component numerical simulation in HTI(LSD) media using the finite element method of the anisotropic elastic wave. By means of the numerical simulation paper revealed the wave field characteristics of the fracture parameters. The conclusion has an important sense for the application of the LSD fracture media model theory in the field of fracture detection and detection of fracture containing fluid.

Aimed at deflection fracturing by oriented perforation, a two-dimensional, non-steady and two-phase Finite Element Method (FEM) is established. Taking a battery of wells in the inverted nine-spot rhombus pattern as object of study, it is reported that law of different crack initiation angle (CIA) affecting deflection fracturing. In the respect of daily oil production and cumulative oil production, the dual fracture with different CIA is more than straight fracture. So it is feasible to use deflection fracturing of oriented perforation to increase the production of the special low permeability oilfield. In contrast to dual fractures with different fracturing initiation angles, we can see that the wider CIA, the higher cumulative oil production. So we can draw such a conclusion that when deflection fracturing is implemented, angle should be increased if the working condition is permitted so as to increase the production of oil well.
