由于常规测井的响应受到诸多因素的影响,因此给定性和定量评价储层的渗透率带来一定的误差。分析表明,结合MDT的压降流度和NMR孔隙度资料能够更加快速而准确地定性评价储层渗透性;将MDT求取的径向渗透率作为分析NMR渗透率的控制点来校正Coates-Timur模型能够大大提高其渗透率的定量解释精度。 Due to the influence of many factors on the response of conventional logging, the qualitative and quantitative evaluation of the permeability of the reservoir brings some errors. The analysis shows that combining reservoir pressure drop and NMR porosity data of MDT can qualitatively evaluate reservoir permeability more quickly and accurately. Radial permeability determined by MDT can be used as a control point for analyzing NMR permeability to correct Coates-Timur The model can greatly improve the quantitative interpretation of its permeability.
