Research and Application of Expansion Evaluation Device for Solid Expandable Tubular

Abstract:

The expansion evaluation device for solid expandable tubular (SET) was researched and designed considering some questions of too little expansion force to flareout SET for a great many other simple expansion devices, too little expansion speed, improper expansion process that don’t match the truth and etc.. The SET can be checked and evaluated through expansion test simulating oil field fact on the expansion evaluation device. Using this device the expansion test can be carried out by only mechanical stretching force or only hydraulic pressure or the combination of mechanical tensile force and hydraulic power. Practice shows that the evaluation devic is characterized by low cost, economic and pragmatic and high reliability. On the other hand some other roles can be get by making use of evaluation device, for example research on deformation law for steel pipe, choice and development of SET’s material, optimization design of expansion cone, study on expansion technology and etc.. The expansion evaluation device will make a great role on promoting SET quality and advance the localization process of chinese SET industry.
