本文以南海某油田为例,探讨应用地震反演资料约束三维储层模型的几种方法。研究表明,综合应用包括地震信息在内的多学科信息进行沉积微相随机建模能有效弥补井间信息不足的缺陷,降低地质模型的不确定性,所建模型能够较好地描述储层微相三维展布特征,为油田生产提供地质依据,也为储层物性预测乃至数值模拟研究提供必要的支持。
Taking the South China Sea oil field as an example, there are several ways for constraining 3D reservoir models using seismic inversion data were discussed in the paper. The research results showed that the multi-disciplinary information including seismic data applied generally to have randomly sedimentary microfaciesmodel building which can make up for not having enough well bore information and decrease the uncertainty of the geological models. The built models can describe the 3D distribution features of reservoir microfacies, which not only can provide geological foundation for oilfield construction but also can support the prediction of reservoir physical property and the research of numerical modeling.
