Latest Patents

Qian Cao 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 matching cover body. The cover body features a vent hole at its center. The cylinder is filled with a compacted sand body, achieving a theoretical porosity of 5%-10%. The filled sand body consists of a mixture of coarse, medium, and fine-grained high-purity quartz sand, along with silicon micropowder and quartz cotton. This innovative combination reduces the porosity and permeability of the standard sample, making it more representative of actual shale geological samples. This advancement is crucial for verifying methods or calibrating instruments used in measuring rock porosity.
