Abstract

As the drilling operation progresses to deeper formations, the downhole environment gradually becomes more complex and variable, which puts higher demands on the performance of the elastic centraliser. The elasticity performance of the core component of the integral elastic centraliser, the centraliser arcualia, is the key index to measure the performance of the whole centraliser. Among them, the reset force of the arcualia and its strain energy density are important parameters for evaluating the elastic properties of the arcualia, and they directly affect the efficiency and reliability of the centraliser. In this paper, a three-dimensional finite element model of borehole-centraliser-casing is established; based on the response surface method, the effects of three structural parameters, namely, the arcualia chord length, wall thickness and arcualia width, on the reset force and strain energy density of the armature are investigated and analysed. and the reliability of the finite element analysis is verified through experiments. The results of the study show that the primary and secondary factors affecting the reset force are: wall thickness, arcualia width and arcualia chord length; and the primary and secondary factors affecting the strain energy density are: arcualia width, wall thickness and arcualia chord length. The results provide a theoretical reference for the analysis of reset force and strain energy density by the geometry of integral elastic centralisers.
