The whole process of clamping offshore well double metal composite pipe was established, Reviewing the problems that in the oil and gas wells the double metal composite pipes frequently get plastic damage or even fracture failure when the power slips hold fast to the double metal composite pipe, the effect Eq. of contact area to tooth plate and double metal composite pipe was deduced, and based on the elastoplastic contact analysis theory, the theoretical Eq. was verified. For the double metal composite pipe stress, displacement and stress of drill tooth plate, influence of slip teeth plate on the double metal composite pipe damage was analyzed, The plastic damage law of the double metal composite pipe was obtained with the influence factor of the contact surface and the influence factor of the tooth crown width. the analysis showed that, The double metal composite pipe can be clamped and the contact area value of the tooth plate with the minimum damage are fixed. Several sets of teeth were produced, and then used to carry out experiments, indoor and field experiments have fully proved the accuracy of the result, The research work provides a better theoretical basis for optimal design of slip tooth plate.
