ASSESSMENT OF STRESS STATE IN ROCKS BY DEFORMATION CHARACTERISTIC OF BOREHOLE ZONE WITH HYDROFRACTURE

摘要

The authors propose the method of stress state assessment in permeable rocks. The method is numerically studied as the relationship between cross-section area of borehole length interval with a hydrofracture and the loading pressure on the borehole walls. The test data processing algorithm and the practical application of the method are considered.
