| Abstract: | Reservoir permeability is one of the important parameters for reservoir evaluation.It plays an important role in oil and gas exploration and is an indispensable reservoir physical property parameter.Nuclear magnetic resonance logging technology has the advantages of rapidity,non-destructiveness,and accurate measurement,which can easily obtain reservoir permeability.According to the development trend of nuclear magnetic resonance permeability calculation methods,the permeability calculation methods based on nuclear magnetic resonance logging were divided into three types:the permeability calculation method based on geometric mean,the permeability calculation method based on cutoff value and the composite method.The advantages and disadvantages of the three methods and the problems they face were discussed,in order to provide ideas for the evaluation of reservoir permeability. |
