With a total of 2 patents, Zhao's work focuses on innovative solutions that address environmental concerns in industrial applications.

Latest Patents

Zhao's latest patents include a low-density, high-strength degradable temporary plugging agent and a surfactant that changes the wettability of tight sandstone. The temporary plugging agent comprises 60% to 85% by weight of polylactic acid, along with starch, polycaprolactone, a solubilizing agent, and a toughening agent. This agent is designed to effectively bridge existing cracks and increase pressure while being fully degradable under formation conditions, thus preventing secondary damage to reservoirs.

The surfactant patent involves a method for altering the wettability of tight sandstone. By combining an aqueous phase solution with an oil phase solution and utilizing an emulsifier, Zhao achieves a uniformly dispersed phase. The resulting surfactant reduces oil-water interfacial tension, transforming oil-wet surfaces into water-wet surfaces, which enhances the flowability of crude oil in low-permeability reservoirs.
