Design and analysis of sealed suspension module based on solid expandable tubular repair technology

다국어 초록 (Multilingual Abstract)

The ability of sealing suspension of solid expandable tubular (SET) is one of the important factors that determine whether pipe can expand normally and serve. To solve the problem that the SET deviates from the original position (causing for the failure to repair of leakage well) due to the insufficient suspension force after expansion, this paper establishes the two-dimensional coupling model of SET-rubber ring-expansion cone-casing based on laboratory experiment parameters, designs the parameters of the sealed suspension rubber ring and conducts simulation. The results show that when the compression amount of the rubber ring is designed to be 47 %-58 % of the rubber thickness, the SET has excellent sealing ability after expansion and can meet the requirements of suspension force; too much compression will affect the service life of the rubber ring. When the length of the rubber ring is 50 mm-110 mm, the driving force and contact pressure during expansion are suitable; the rubber ring spacing is designed to be 110 mm, which avoids interference after rubber compression and saves material. In addition, the vulcanizing bonding strength of the rubber ring should be greater than 120 kN to avoid peeling off due to the failure of the rubber ring and SET bonding. The research results of this paper provide a theoretical basis for the design of sealing suspension module of SET repair technology.
