Latest Patents
Xiaoqing Li's latest patents include the "Amphiphilic block polymer ultralow-permeability agent" and "intelligent temporary plugging type water-based drilling fluid." These inventions relate to the technical field of oil and gas drilling. The ultralow-permeability agent comprises a structural unit provided by styryl hydrophobic monomer, maleic anhydride, and acrylamide. The drilling fluid contains a mixture of water, sodium bentonite, and other components, which work together to improve the efficiency of drilling operations. The amphiphilic block polymer allows for self-adaptive characteristics, effectively filling temporary plugging layer gaps and significantly reducing permeability.
Another notable patent is the "calcium-resistant zwitterionic polymer," which includes a preparation method and application. This polymer serves as a dispersing agent in water-based drilling fluids. It contains various structural units that enhance its performance, with a weight-average molecular weight ranging from 350,000 to 600,000.
