Abstract: The article gives the recommendations of a technical solution for preventing the destruction of external surfaces of drill and casing pipes by wedge grippers in the process of performing descending-lifting operations. Also, a constructive solution to clamping the surface of the pipes during screwing or unscrewing of thread connections is proposed. The research of proposed technical solutions of grippers using computer models has been carried out. The main parameters of the design elements of the proposed wedge gripper and clamp are established, which can provide the technological process without destroying the outer surfaces of the pipes of the oil assortment.
