摘　　要：在工程精度条件下,将套管外挤压力达到稳定的时间与地层介质的松弛时间联系起来,进而与地层黏度联系起来,建立了一个用测井资料估算地层黏度的公式.使用这个公式估算,扶余油田西区地层黏度为10^(17)Pa.s数量级,乾安油田为10^(16)Pa.s数量级,与岩石试验和地球物理方法得到的地层黏度范围吻合.Within engineering accuracy, the time for the casing external extrusion pressure reaching a stable value is related to the relaxation time of the stratum, and further to the viscosity of the stratum. An expression to estimate the： viscosity of stratum using logging information is proposed. Applying this method, the order of magnitude of viscosity of stratum in west zone of Fuyu oilfield and Qian＇an oilfield is estimated as 10^17 Pa.s and 1016 Pa.s, respectively, as is consistent with the range of viscosity of stratum obtained by rock test and geophysical method.
