Abstract
A standard sample for measuring rock porosity by helium method is disclosed, which includes a cylinder body open above and a cover body matching the cylinder body. The center of the cover body is provided with a vent hole. The cylinder body is filled and tamped with filled sand body so that theoretical porosity in the cylinder body is 5%-10%. The filled sand body includes mixed sand body and quartz cotton. The mixed sand body includes coarse-grained high-purity quartz sand, medium-grained high-purity quartz sand and fine-grained silicon micropowder. By mixing, filling and tamping high-purity quartz sand with different particle sizes, silicon micropowder and quartz cotton, the porosity and permeability of the standard sample are reduced, so that the standard sample is closer to the physical properties of the actual shale geological samples to verify the method or calibrate the instrument for measuring rock porosity with helium method.
