【Abstract】 The ultra-low permeability measurement is a hot issue in the oil area. With the development of low-permeable oilfield, and with the production of coalbed methane and shale gas, the measurement of ultra-low permeability has being paid increasing attentions. Based on related literatures at home and abroad, this paper summarizes the methods of measuring ultra-low permeability at present, and introduces the working principles of each method respectively. Moreover, this paper gives a brief summary of their advantages and disadvantages.更多还原
