| Abstract: | According to the flaws of the two present conventional cementing techniques through inner tube, the cementing plan through flexible inner tube is designed, and the feasibility of the plan is analyzed and proved. Based on the feasibility analysis results, two types of tools are developed for cementing through flexible inner tube. The working principle and using method of the tools are described, as well as the cementing process. And the cementing procedures of the novel cementing techniques are illustrated. The ground experiments and field tests show that the cementing work can be successfully carried out through the novel techniques, indicating the novel technique can overcome the flaws coming from the conventional cementing technique through inner tube, and it can improve the success ratio of cementing techniques through inner tube for wells with large radius casing |
