Patent number: 11905221Abstract: A dispersant for premixed fluidized solidified soil includes the following raw materials in parts by weight: 5 parts to 15 parts of an anti-adhesion water reducer, 0.5 parts to 0.8 parts of a stabilizer, and 85 parts to 95 parts of water. The anti-adhesion water reducer is compounded by an inorganic dispersant and an aminosulfonic acid-based superplasticizer (ASP), and the inorganic dispersant is at least one selected from the group consisting of sodium silicate, sodium hexametaphosphate, and sodium pyrophosphate. In the present disclosure, on the premise of improving fluidity of mucky cohesive soil slurry, a strength of the fluidized solidified soil at each stage is adjusted through a water-reducing effect of the anti-adhesion water reducer. Moreover, rapid dispersion of the mucky cohesive soil slurry is realized, thus providing key technical support for preparation of the premixed fluidized solidified soil from undisturbed soil in non-dry conditions.Type: GrantFiled: May 11, 2023Date of Patent: February 20, 2024Assignees: WUHAN INSTITUTE OF TECHNOLOGY, THE COLLEGE OF POST AND TELECOMMUNICATION OF WITInventors: Zunqun Xiao, Caiyun Xu, Hui Wang, Fuqi Wang, Zhentao Lv, Yanbin Chang, Haitao Liu, Yinlei Shi, Keqi Luo, Jian Lin, Minghui Deng, Puyu Li, Yuepeng Zheng

Patent number: 11035228Abstract: A simulation test system for gas extraction from a tectonically-deformed coal seam in-situ by depressurizing a horizontal well cavity. A coal series stratum structure reconstruction and similar material simulation subsystem simulates a tectonically-deformed coal reservoir. A horizontal well drilling and reaming simulation subsystem constructs a U-shaped well in which a horizontal well adjoins a vertical well, and performs a reaming process on a horizontal section thereof. A horizontal well hole-collapse cavity-construction depressurization excitation simulation subsystem performs pressure-pulse excitation and stress release on the horizontal well, and hydraulically displaces a coal-liquid-gas mixture such that the mixture is conveyed towards a vertical well section. A product lifting simulation subsystem further pulverizes the coal and lifts the mixture. A gas-liquid-solid separation simulation subsystem separates the coal, liquid and gas.Type: GrantFiled: November 12, 2018Date of Patent: June 15, 2021Assignees: China University of Mining and Technology, XUZHOU OLIVINE GEOSCIENCE & GEOTEC CO., LTD., CHINA UNIVERSITY OF PETROLEUM, EAST CHINA, ANHUI UNIVERSITY OF SCIENCE AND TECHNOLOGY, WUHAN INSTITUTE OF TECHNOLOGYInventors: Shuxun Sang, Haiwen Wang, Xiaozhi Zhou, Liwen Cao, Shiqi Liu, Huihu Liu, Zicheng Li, Jinlong Jia, Huazhou Huang, Changjiang Liu, Hongjie Xu, Ran Wang, Shuyun Zhu
