Abstract

Abstract:

A model that is used to casing radial deformation of horizontal well by finite element analysis method of 3D pipeline and 3D shell .The axial load effect to casing radial deformation provide is considered a new academic bases for curve hole casing designing. Diameter 244. 47 mm casing is taken as a case, casing radial to three kinds of conditions in curve secession: no stabilizer calculated, and casing string contacts hole; with stabilizers, and casing string stays in the center; between stabilizers casing string contacts hole occasionally. The results have been used to 244.47 mm casing design of high curve horizontal well in the Kelamayi oil field.

Key words: Horizontal well, Crooked hole, Casing deformation, Casing string design, Mathematical simulation
