Latest Patents

Yeyu Zhang holds a patent for a "Standard sample for measuring rock porosity by helium method." This invention includes a cylinder body that is open at the top and a cover body that matches the cylinder. The cover body features a vent hole at its center. The cylinder is filled with a tamped sand body, achieving a theoretical porosity of 5%-10%. The filled sand body consists of mixed sand and quartz cotton, which includes coarse, medium, and fine-grained high-purity quartz sand. By carefully mixing and tamping these materials, the porosity and permeability of the standard sample are minimized, making it more representative of actual shale geological samples. This innovation is crucial for verifying methods or calibrating instruments used in measuring rock porosity with the helium method.
