The utility model relates to the technical field of core permeability determination, specifically is a kind of core
gas phase permeability determination device with auxiliary function, including bearing plate,
gas phase permeability determination mechanism, gas conveying mechanism and
data display mechanism, the
gas phase permeability determination mechanism fixedly connected in the middle portion of bearing plate top portion. In the utility model, through the setting of clamping plate,
pressure sensor and heating sleeve, the stable clamping of different size cores is realized, clamping plate is driven under the
regulator, can tightly adhere to the surface of core, and three clamping plates are symmetrically arranged in three equal parts, can provide uniform and stable clamping force in the circumferential direction of core, effectively prevent core displacement or shaking in the experimental process, avoid gas leakage or measurement error due to core loosening,
pressure sensor real-time monitoring clamping pressure, data is fed back to
data terminal controller, the
cooperative work of heating sleeve and temperature sensor can accurately simulate formation temperature.
