HTHP Permeameter, TG-3021 manufactured by Shenyang Taige Oil Equipment is designed for oil well cement test. HTHP Permeameter determines the permeability of cement stone and core specimens using dry nitrogen through formation samples. Applying Darcy’s law, the permeability can be determined by measuring the differential pressure gap of the core specimen and the velocity of nitrogen through the core. HTHP Permeameter is equipped with a cylindrical core holder with a diameter of 1 inch and a length of 1 inch. HTHP Permeameter has the advantages of simple operation, good durability and low cost.
