Research of the Radial Strength of a Composite Matrix of a Cable-Pusher for Oil Wells

Abstract

As a result of experimental studies, data on the maximum radial loads for a cable with a carbon matrix and the effect of copper conductors on the crack formation process under radial loading of a pusher cable were obtained at the temperature of 20 °C. A finite-element model of a pusher cable is developed, which takes into account the presence of a matrix, copper conductors, and their insulation, which allows us to construct stress and strain fields. The created finite element model allows you to predict maximum loads for composite pusher cables. The design of a stand for testing samples of cables with carbon matrices for radial compressive strength is described. Experimental data on the study of the strength properties of two types of cables at a temperature of 20 °C are presented.
