In Situ Stress Field

Information of in situ stress field is crucial for predicting the response of rock masses to the disturbance associated with underground constructions. Hydraulic fracturing is an efficient method for determining the stress field and is suitable at the early stages of projects when no underground access exists. For this, a series of new improved techniques and equipments are developed for the deep boreholes to increase the reliability of system. For a better understanding of the stress test, the ideal HF pressure-time curve is given and the fracturing procedure is analyzed. Based on the theory of HF stress calculation, two implicit inequations are deduced.
