Title: Innovations of Xiaojia Xue in Surfactant Technology

Introduction

Xiaojia Xue is a notable inventor based in Beijing, China. He has made significant contributions to the field of surfactant technology, particularly in enhancing the wettability of tight sandstone. His innovative approach has implications for improving oil recovery in low-permeability reservoirs.

Latest Patents

Xiaojia Xue holds a patent for a surfactant that changes the wettability of tight sandstone and its preparation method and application. The patent describes a process where an aqueous phase solution is added to an oil phase solution. Under the action of an emulsifier, a uniformly dispersed phase is achieved. An initiator is then added, followed by stirring and raising the temperature to react the mixture, resulting in a colorless and transparent liquid, which is a high polymer. At room temperature, a fluorocarbon surfactant and biosurfactant are added, and stirring continues for four hours to obtain the final surfactant product. This surfactant effectively reduces oil-water interfacial tension, transforming oil-wet surfaces into water-wet surfaces, thereby improving the flowability of crude oil in the original stratum.
