Loading and Axial Deformation of Finite Element Analysis of Down-Hole Strings Used for Hydraulic Fracturing

Abstract:

The string is loaded by ground thermal stress, fluid squeeze pressure and gravity in horizontal wells in the process of fracturing. The fluid-solid heat coupling theory is used to make the theoretical feasibility analysis on the column simulation of the fracturing string. Fracturing string is analyzed on the suitable physical model which is set parameters, boundary conditions and constraints on the basis of actual condition by the finite element method. And it is made by different formation temperature load coupling analysis. The tubing analysis focuses on axial stress, axial deformation, and the relationship between axial stress and circumferential stress. So, it obtains the change rules of string in the process of fracturing which directly compared results of the theoretical calculation of the force produced by the axial deformation. It proves the feasibility of this method. So the paper provides a basis for guiding the production process of fracturing string, which can improve the effect of fracturing operation.
