Expandable Tubing R&D on the Material of FMA Multiphase Alloy Steel

Abstract

Basing on the performances analysis of the expandable tube material, the paper introduces the FMA multiphase alloy steel, the new type of expandable material. The conclusions were presented at the detailed analysis of material microstructure, chemical composition, heat treatment, mechanical properties and other aspects. This paper will promote the application of this new material.

Study on the Technology of Solid Expandable Tubular in Open-Hole Well

“…After decades of development, it has achieved tremendous development in plugging, repairing casing, and optimizing the wellbore structure [4]. In recent years, a large number of scholars and engineers have conducted research on many aspects of the technologyThey mainly focused on the selection of materials, the optimization of the expansion cone, the collapse after expansion, the expansion force, etc., and achieved remarkable achievements [5][6][7][8][9][10][11][12][13][14]. In general, there are few studies on open hole wells, and these studies are mainly on casing damaged wells [15].…”
