APPLICATION STUDY OF THREE DIMENSIONAL GEO-STRESS MEASUREMENTS BY USE OF HYDRAULIC FRACTURING METHOD

The theoretical model created based on minimum principal stress criteion is a new thinking of the three dimensional geo-stress measurements made by hydraulic fracturing method. According to the theoretical study and in consideration of real situation of test, this paper emphasizes on the influence of observed dsts error on test results in detail,and confirm the reliability and applicability of this method resalting from the theoretical model for three-dimensional geo-stress measurements.
