在渗透率测定技术中,当用气体作为测定流体的时候,必需修正气体滑移的影响,用液体时,必须注意这个液体与岩样颗粒不起反应,由于岩心取样后外加压力的降低而引起的渗透率变化亦需加于校正。
In permeability measurement techniques, the effect of gas slip must be corrected when using gas as the measuring fluid. When using liquids, care must be taken that this liquid does not react with the rock particles and is caused by a decrease in applied pressure after core sampling The permeability changes also need to be added to the calibration.
