During the reservoir exploration, it is very difficult to determine the tight sandstone′s klinkenberg permeability because of its very low permeability. Permeability of reservoir rock is an important parameter for reservoir exploration. To determine the tight sandstone′s permeability fast and accurately, the paper introduces the instrument′s determining principle, system structure, technical specification, overall control system and contrasting method with studies. The instrumental error is in the scale of allowable error through contrasting measurements. The instrument is ideal for determining the low-permeability reservoir′s permeaility.
