| 摘 要： | 基于Kuster-Toksoz岩石物理模型和Biot流体饱和多孔介质中的波动理论,运用波场仿真,研究了薄互层油藏长期水驱过程中地震响应的变化特征.结果表明:①薄互层油藏单层水驱作用引起的地震响应变化一般较弱;②多层同时水驱的情况较为复杂,但各层水驱结果具有累积效应,产生的地震响应变化相当明显,即使在孔隙度较低的情况下,引起的地震响应的变化也是可观的;③薄互层油藏多层水驱地震油藏监测是可行的.

| Abstract: | The applicability of seismic monitor for water injection recovery processes in the excessive heterogeneity of continental alternate thin-beds reservoir was investigated.Based on Kuster-Toksoz rock physical model and Biot theory for fluid-saturated porous elastic medium, the behaviors of seismic response of the water injection recovery processes in alternate thin-beds reservoir were discussed using wave simulation.The results show the following conclusions. ①Generally,the change of seismic response of time-dependent reservoir is small for a single layer of water-flooding reservoir.②Although it is more complicated for multi-layer water-flooding reservoir simultaneously,it has cumulative effect and the change of seismic response of time-dependent reservoir is notable in general,even if the reservoir has a little porosity.③It is applicable to monitor the water injection recovery processes in alternate thin-bed reservoir by seismic method. |
