DETERMINATION OF IN-SITU STRESSES IN ANISOTROPIC STRATA AND PREDICTION OF BREAKDOWN PRESSURE ACTING ON DEEP WELL-WALL
各向异性地层应力的推算及深孔地层破裂压力的预测

The computational formulas are given for determination of in-situ stresses inanisotropic strata. On the basis of given formulas the formula for determination ofbreakdown pressure is given. The determination process of elastic parameters by using thevertical seismic profiling data is proposed. The detecting example using above process ispresented.
