Abstract:Several methods of borehole stress measurement are briefly reviewed. A new goestress measurement method,called local borehole-wall complete stress relief method(LBWCSRM),is proposed in this paper. This method has marked advantages of no need of overcoring and no other assumption when calculating the crust stress tensor. Theoretically,the application of this method is free from the limitation of borehole depth and versatile for any deep boreholes. So it offers an innovative approach to stress measurement at great depths.
