Patent number: 11787990Abstract: The present invention relates to the field of petroleum industry phase oilfield chemistry, and specifically relates to a bionic and dual-phobic drilling fluid. The drilling fluid contains a bionic wall-fixing agent, a bionic lubricant, a super dual-phobic agent, a scrap-carrying agent and a bionic shale inhibitor. The present invention uses the theory of bionics and the theory of a downhole rock surface being double phobic as a basis. By means of using the bionic wall-fixing agent, the bionic lubricant, the super dual-phobic agent, the scrap-carrying agent and the bionic shale inhibitor, which have special properties of imitating animals and plants in nature, and using a series of bionic treatment agents, a set of bionic and dual-phobic drilling fluid systems, which corresponds to an unconventional, complex oil and gas well, is formed.Type: GrantFiled: December 30, 2022Date of Patent: October 17, 2023Assignees: China University of Petroleum (Beijing), CNPC Chuanqing Drilling Engineering Company Limited, CNPC Engineering Technology R&D Company LimitedInventors: Guancheng Jiang, Jinsheng Sun, Yinbo He, Xin Zhang, Chunyao Peng, Tengfei Dong, Bin Tan, Tie Geng, Lili Yang, Xiaohu Luo, Xuwu Luo, Xing Liang, Changwei Chen, Xiaobo Liu, Rongchao Cheng, Jiansheng Luo, Jianguo Zhang, Yong Wang, Daqi Fu, Qifa Ran, Li Zhao, Kaixiao Cui, Xiaoxiao Ni
