| 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$\cdot$s数量级，乾安油
田为$10^{16}$\,Pa$\cdot$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.

| Abstract: | 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}$\cdot${s} and
$10^{16}$\,{Pa}$\cdot${s}, respectively, as is consistent with
the range of viscosity of stratum obtained by rock test and geophysical method. |
