    Abstract:

    The working situation of wire-line core drilling is analyzed and three-dimensional simulation are made on the stress states on wire-line core drilling pipe and connection joint based on ANSYS. Through the numerical simulation, the position of maximum stress on the drilling pipe in different working conditions is presented, which have certain reference value to prevent drilling pipe breaking, optimize the design of connection joint thread and determine reasonable drilling parameters.
