The determination of formation fracture pressure and the geometry of hydraulic fracture is critical for designing rational fracturing program, providing optimal operation pressure, avoiding interzonal crossflow caused by excessive fracture height, and better stimulating the reservoirs.

确定地层破裂压力和水力压裂裂缝延伸几何形态，对于设计合理的压裂方案、提供合理的压裂施工压力、避免压裂裂缝高度过高导致地层间的层间窜漏、更好地达到改善储层的目的至关重要。

In combination with the geological features of the ga wells in West Sichuan, such as multi-payzone high pressure gradients and a large lithological change in channel sand bodies, etc., the casing cementing and perforation completion were adopted for the main well and branch holes in the well group and the interzonal pressure seals of the main well and branch holes, and the separate well fracturing and producing were all realized through a completion string with dual-tubing and dual-packer.

Two special cases are discussed: flow due to a constant pressure gradient and flow due to a periodic one; In chapter 4, on the basis of the method of fractional element proposed by Schiessel et al and of the generalized fractional element networks proposed by Xu and Tan and by the use of discretization method for solving the inverse Laplace transform, we obtain the creep compliance of Zener and Poynting-Thomson models which are composed of the generalized fractional element networks.

Second, transient flow for vertical well and fractural well in porous media with arealanisotropy has been researched in this paper. The analytic solution for vertical well andsemi-analytic solution for vertical fractural well is developed by using image inversion,superposition principle, Laplace transformation, Fourier transformation, as well as theirinverse transforms, and storage and skin are taken into account. For vertical fractural well,influence of pressure and productivity is studied when the orientation of artificial fractureisn't in accordance with the direction of major permeability, it is fundamental to evaluatepotential and analyze well test data.
