摘要

BISQ模型是由Biot流动和喷射流动两种力学机制结合起来构成的。基于BISQ模型,分析了双相介质中波的传播规律、波场特征以及喷射流动对地震波场的影响。地震波通过油气层时会引起储层顶底及横向上能量分布的差异,因此可以通过快纵波的逆品质因子和吸收系数的横向变化来进行油气检测。某地区碎屑岩储层含油气性检测的应用研究表明,该方法能够准确而有效地检测出油气的空间分布,为油气检测提供了一种新的技术手段,具有广阔的应用前景。
BISQ model is composed of fluid-solid action mechanics between Biot flow and jet flow.Based on BISQ model,wavefield features,propagation rule,strong attenuation and high frequency dispersion of seismic wave caused by jet flow in dual phase media are analyzed.Based on the particular seismic wavefield properties of dual phase media,when seismic wave penetrates the reservoir,the energy of top,bottom and lateral orientation of the reservoir will be different.So,the fast P wave′s Q-1 & αcan be calculated to detect hydrocarbon.This method is applied to detect hydrocarbons in clastic rock reservoir,oil/gas special distribution in the study area were detected accurately and effectively.Moreover,the detection results are verified by the actual drilling results.This method has provided a new technical support for oil/gas detection and has wide application prospects.
