气测渗透率与油测渗透率一般都存在一定的差异，对低渗储层尤其明显。通过实验测定了鄂尔多斯盆地 Hq、Zb、Hs 等3个区块岩心的气测渗透率与油测渗透率。实验结果表明，渗透率越低，气测渗透率与油测渗透率的差距越大；致密储层、超低渗储层、特低渗储层以及一般低渗储层的气测渗透率与油测渗透率的差距明显不同，因此该差距可以作为划分储层的一个界限；气测渗透率与油测渗透率的差距与黏土矿物、润湿性、比面等因素显著相关。

There is usually difference between gas measuring permeability and liquid measuring permeability,particularly in low permeability reservoirs.Hq,Zb and Hs of the gas permeability and liquid permeability were measured by experiments in the Ordos Basin.The results of experiment show that the lower the permeability was,the bigger the gap between the gas permeability and liquid permeability was.The gap of the oil measuring permeability and gas measuring permeability was obviously different among tight reservoir,super-low permeability reservoir,ultra-low permeability reservoir and low permea-bility.Therefore the result could be used as a demarcation to divide reservoir.The gap of gas permeability and oil permeability had a great relation to the clay mineral,wettability and surface area to the volume ratio.
