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 ;
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.
