A New Method to Estimate Rock Mechanics Composed both the Dynamic and Static Test Means

Abstract:

The reasonable estimate of rock mechanics is extremely important to the design of hydraulic fracture, but the direct triaxial test is a high consumption of time and money. The relation between the dynamic rock mass parameters and the static ones could be used to establish a new method to assess rock mechanics. This new method which was composed by some formulations generated by the well logging data and the Hoek-Brown criterion with the iterative computation way could provide calculated GSI, Young modulus and Poisson ratio data. These data has a little deviation, less than 10% which can be acceptable in project scope, with triaxial test value of rock core. As a result, this method has been proved to be easy and credible to use.
