时移地震非线性反演压力与饱和度变化研究
|
摘要
在现有研究基础上提出基于岩石物理模型和混合优化算法的时移地震反演压力、饱和度变化方法.介绍了混合优化算法原理和适用于疏松砂岩的岩石物理模型,建立了非线性反演油藏参数变化的流程.将本方法用于某油田实际数据标定的疏松砂岩岩石物理模型,分析三组地震属性组合与油藏参数的敏感性并进行油藏参数非线性反演,结果表明敏感性不同的三组地震属性组合均能得到正确结果,表明了方法的稳定性与有效性.油藏参数反演结果整体误差小,证明非线性反演方法不受油藏参数变化范围的影响,优于线性化反演方法.
A new pressure and saturation change nonlinear inversion method is proposed using time-lapse seismic data,which is based on hybrid optimization method and rock-physics model.The hybrid optimization method and rock-physics model used in this paper are discussed.The nonlinear inversion process is given.The new method is tested with rock-physics model calibrated with real field logging data.The sensitivity and inversion results are compared for three kinds of seismic attributes combinations.It shows that the inversion method is stable and robust and inversion precision is higher than linear inversion method.
