Well testing steel wire fatigue simulation device and method

The invention discloses a well testing steel wire fatigue simulation device and method, and belongs to the technical field of petroleum industry downhole tool testing. The well testing steel wire fatigue simulation device comprises a bracket, an upper pulley, a lower pulley, a winch and a counterweight member, wherein the upper pulley, the lower pulley and the winch are fixed on the bracket; the upper pulley is located above the lower pulley, and the lower pulley and the winch are located on the same horizontal plane. By adopting the well testing steel wire fatigue simulation device and the method provided by the embodiment of the invention, the bearing condition of a well testing steel wire in the field operation is simulated through using the counterweight member, and the upper pulley and the lower pulley are matched with the winch to simulate the repeated stretching and abrasion conditions of the well testing steel wire in the field operation, so that the simulation of the field operation conditions of the
