Abstract: [Objectives]The magnitude and direction of in-situ stress are important parameters for well placement， fracturing design and reservoir evaluation in hot dry rock development. It is of great significance to study reservoir stress state for hot dry rock development. [Methods] In this paper， the characteristics of current stress field in Gonghe Basin are analyzed based on regional geological structure evolution， focal mechanism solution and inversion results， statistics of joints and fissures， and ... More
