Latest Patents

Ren's latest patents include a direct method for manufacturing large model fractured cores while maintaining original oil-water saturation. This method involves several steps, such as determining the volume, porosity, and permeability of the fractured core, preparing simulated oil, and mixing oil, water, and emulsifiers to create an oil-in-water emulsion. The process culminates in solidifying the cement sample to achieve the desired core characteristics.

Another significant patent is the manufacturing method of a big-model low-permeability microcrack core. This method includes determining the size of the core, baking stones to create a thin oil film, and mixing the oil-sprayed stones with quartz sand and cement. The final steps involve pouring the cement paste into a core mold and applying confining pressure to adjust the core's porosity and permeability.
