The seismic responses caused by different reservoir parameter variations are numerically simulated, and then the feasibility of discriminating different reservoir parameters and realizing quantitative interpretation using time-lapse seismic AVO technique is ensured. Based on Aki and Richards’ simplified AVO equation, the formula of P-P wave and P-S wave for time-lapse seismic AVO was derived in details. According to the rock physical model of S oil field and the formula acquired, the multiple time-lapse seismic AVO inversion equations are achieved to discriminate the changes of oil saturation and effective pressure. It is shown by simulated data experiment that the time-lapse seismic AVO inversion is feasible, and the formula derived in this paper is effective to discriminate the changes of oil saturation and effective pressure, and to improve the precision of time-lapse seismic interpretation.

:油藏盖层各向异性在油藏开发前后对地震AVO 曲线有相同程度的影响,而这种影响能否在2次地震 AVO曲线相减后变得很小,可以被忽略?利用某油田数据建立了储层岩石物理模型,根据Gassmann方程获得 了该油田储层的纵、横波速度与含油饱和度的关系曲线。设计了双层油藏模型,通过求解横向各向同性(VTI) 介质界面的透射系数与反射系数的线性方程组,计算了油藏盖层存在各向异性时的P P波和P S转换波反射 系数,分析了不同Thomsen参数对反射系数及其油藏开发前后反射系数差异的影响,并进行了定量分析。分析 结果表明,小入射角情况下进行P P波时移地震AVO 分析,可以忽略盖层各向异性的影响;大入射角情况下 进行P P波时移地震AVO和多波时移地震AVO分析,盖层各向异性不能忽略。

数值模拟了油藏含油饱和度与有效压力变化时移地震AVO 的响应,确定利用时移地震AVO 区分油藏参 数的变化、实现油藏定量解释的可行性. 从Aki 等AVO 近似方程出发,详细推导了P- P 波和P-S 转换波时移地震 AVO 计算公式. 结合岩石物理近似关系和本文推导的时移地震AVO 计算公式,推导了利用多波时移地震AVO 反演 油藏含油饱和度和压力变化的方程. 数据试验表明,文中推导的多波时移地震AVO 方程能较好地反演油藏含油饱 和度变化和有效压力变化,实现油藏定量解释.
