Patent number: 11567018Abstract: A performance evaluation device and a design method of a cement for well cementing in a penetrated hydrate layer are provided. The performance evaluation device includes an equivalent wellbore, an inner circulation system, an outer circulation system, a thermal insulation cover, a bracket, a temperature sensing system, and a cement mold. The device can simulate a true downhole situation, conduct an evaluation experiment on the heat insulation performance of a cementing cement, and conduct experiments at different temperatures with automatic temperature control. The design method is to use a low-hydration, early-strength, and heat-insulating cement slurry system during the well cementing in a penetrated hydrate layer, where the low-hydration and early-strength characteristics ensure the effective sealing of a hydrate layer during a cementing process, and the heat insulation characteristic results in low heat conductivity and thus can ensure the stability of a hydrate layer during a production operation.Type: GrantFiled: January 21, 2022Date of Patent: January 31, 2023Assignee: CHINA UNIVERSITY OF PETROLEUM (EAST CHINA)Inventors: Huajie Liu, Yuhuan Bu, Shenglai Guo, Chang Lu, Xinyang Guo, Shengda Shen, Rui Ma
