Physical modeling of deformation and filtration processes in low-permeability reservoir rocks when implementing the directional unloading method

This article describes the results of physical modeling deformation and filtration processes in low-permeability reservoir rocks Achimov deposits Urengoy gas condensate field. The experiments were carried out on a unique true Triaxial Independent Loading Test System (TILTS) Institute for Problems Mechanics Russian Academy Sciences. effect non-uniform triaxial stress state character was studied. Real stresses that occur bottomhole formation zone when pressure well decreases created rock specimens. Experiments to simulate at walls open hole tip perforation hole. geomechanical approach is shown be promising creating ways improve quality wells; particular, adaptation directional unloading method conditions given considered. These studies are essential both fundamental scientific practical terms substantiate technological solutions development fields with reservoirs.
