Title: Innovations of Donghe Yu in Phase Change Fracturing Technology
Introduction
Donghe Yu is a notable inventor based in Cangzhou, China. He has made significant contributions to the field of phase change fracturing technology, holding a total of 2 patents. His work focuses on developing advanced fluid systems that enhance the efficiency of hydraulic fracturing processes.
Latest Patents
One of Donghe Yu's latest patents is a phase change fracturing fluid system designed for phase change fracturing. This invention includes various components in specific weight percentages, such as 10%-40% supramolecular construction units, 0-40% supramolecular function units, and other additives. The supramolecular construction unit can be melamine or triallyl isocyanurate, while the function unit may include vinyl acetate or acrylonitrile. The solvent options include methylbenzene and xylene isomers. The process involves initially using a conventional fracturing fluid, followed by the injection of the phase change fracturing fluid into the formation.
Another significant patent is the phase-change hydraulic fracturing process. This process consists of several steps, including the injection of clean water or conventional fracturing fluid to fracture the formation, followed by the simultaneous injection of non-phase-change and phase-change liquids. The method ensures that solid-phase materials generated by the phase-change liquid are effectively laid in the fracture, completing the construction through a well shut-in and pressure-out phase.
