Well stimulation on the basis of preliminary triaxial tests of reservoir rock

摘要

The purpose of the paper is the presentation of the geomechanical approach to the developmentrnand the improvement of methods for increasing well productivity and reservoir recovery. Control stress-strainrnstate in the vicinity of awell to enhance the permeability of thewell drained zone increases significantly efficiencyrnof stimulation of a well. It is carried out by directed unloading of the reservoir on the basis of knowledge ofrnthe deformation, strength and filtration properties of specific field rocks. Examination of rock mechanicalrnproperties is made by laboratory tests of rock samples at the true triaxial apparatus. The methodic and the resultsrnof laboratory studies of rocks and of pilot field works on wells are presented on the example of a specific field.rnThey have shown high efficiency of this approach.;
