Abstract:
At present the hydraulic fracture is the most effective and
frequently used method. The modeling of this process is a serious
problem and is very important for prognostication the operation
efficiency. Calculation of local stressed state of porous media
and liquid flows is necessary for the design hydraulic fracture.
In this article the set of processes in the saturated porous media
is considered according to the quasi-stationary Biot model, and
the Coulomb–More criterion used for modeling the crack evolution.
The geological medium is essentially non-homogeneous. The
non-orthogonal and multiblock grids adapted to the formation
structure are used and the support operator method is developed
for the approximation of the Biot equations.
