Research progress on technology of solid expandable tubular

As the development of the Oilfield,the casing of the wells damaged severely day after day.This article introduced the normal methods of casing damage remediation and solid expandable tubular,especially introduced the developing progress about solid expandable tubing by Shengli Drilling Institute.Because of the restriction of the normal methods just as waved pipes and thick wall pipes in the area of drift ID,strength and length,Shengli Drilling Institute developed a new remediation called solid expandable tubing to remedy the failure casing.The solid expandable tubing can remedy hundreds and even thousands meters of failure casing and got much more ID and strength.The research progress of about solid expandable tubing leaded such area of research.It finished the development of material,structure,connection,hanger,seals of the expandable and so on.It even finished the experiment of the simulation and fields.The success of the development of solid expandable tubing can provide a wide method of remediation of the old wells in the oilfield.
