摘要：

ISRM suggested method for step-rate injection method for fracture in-situ properties (SIMFIP) quantify both discontinuities, hydraulic and mechanical properties in situ using coupled pressure/deformation measurements in boreholes. This method can be applied for in situ estimations of fracture properties associated with a wide range of rock stability problems such as rock slope gravitational stability or fracture and fault reactivation induced by downhole industrial fluid injection or production. Sealing of the borehole test interval is accomplished by use of two inflatable rubber packers, spaced apart a distance equal to at least six times the hole diameter. To capture the three-dimensional deformation of a fracture, a borehole extensometer must be centered along the axis connecting the two packers in the injection chamber. Pressure sensors are installed to monitor independently the pressure variations in the test interval as well as above and below the straddle packer system to monitor the injection pressure build up in the interval.
