    Abstract
  • The dynamic mechanical behavior of carbonate rock subjected to dynamic impact in in-situ formation is one of the basic understandings for the large-scale development of carbonate reservoirs. In this paper, the dynamic mechanics of carbonate rock under true triaxial confining pressures was experimental investigated by 3D Hopkinson pressure bar system. During the experiment, the carbonate rock specimens were under the true triaxial confining pressures and loaded dynamically in one incident bar. The dynamic strain rate and dynamic compressive strength of carbonate rock under true triaxial confining pressures were obtained to characterize the differences in the three vertical directions. The results demonstrate that only microcracks appear in true triaxial confining carbonate rock subjected to the dynamic loading.
