In this paper, based on the elastic-plastic finite element theory, the finite element model of expansion process for Solid Expandable Tubular is established, the axial length shrinkage,expansion force,residual stress and collapse strength after expansion are studied.According to the finite element simulaition results and practical experience, the optimum velocity of expansion cone is from 6 m/min to 9 m/min, which provides a theoretical basis and reference for the design of Solid Expandable Tubular.

“…The system incorporates an expandable liner hanger body with an integral packer, a tieback polished-bore receptacle, a setting-sleeve assembly, and a crossover sub to connect the assembly to the liner. 1 Elastomeric elements are bonded on to the hanger body. As the hanger body is expanded, the elastomeric elements are compressed in the annular space.…”

TX 75083-3836, U.S.A., fax 1.972.952.9435. AbstractLiner hangers and liner-top packers traditionally have been used in liner completions. However, in the conventional systems that employ "cone and slip" technology, the failure rate of the liner top packers as well as the failure of system installation has been an ongoing problem. In conventional systems, mechanical equipment with multiple slips are run and set. The disadvantages of these systems include multiple leak paths, reduced radial clearance, and exposed hydraulic ports, all of which increase the potential for failure. When these failures occur, the cost of the well completion is significantly impacted, and well completion efficiency is decreased.Reasons for unsuccessful liner installations can be attributed to a number of conditions, such as:1. the liner cannot be run to depth 2. the liner hanger/packer pre-sets 3. the setting tool fails 4. the liner top cement job is poor. This paper will discuss an expandable liner system that was developed to address the shortcomings of the traditional systems. The new liner system combines expandable solid liner technology with proven cementing products and service capabilities.The following discussion will include details concerning development of the design, operating procedures, and benefits of the expandable liner hanger as well as how the versatility and adaptability of the system improves its reliability. Several case histories will be discussed to verify the efficiency of the new system.
