Abstract
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.
