摘要
建立沉积微相模型不仅能够定量预测沉积微相的空间展布, 而且可以为“相控”“”储层参数模拟提供基础。任何建模方法都有一定的应用范围, 目前没”“”储层参数模拟提供基础。任何建模方法都有一定的应用范围, 目前没有够直接建立海底扇沉积微相模型的模拟方法。针对阿尔及利亚Zarza itine油田海底扇沉积特点和相建模方法的适用范围, 提出了分步建立沉积相模型的方法。选择相序模拟法建立海底扇亚相模型; 分别应用基于目标和指示克里金模拟方法建立中扇微相和下扇微相模型; 在亚相模型的约束下, 将中扇微相模型和下扇微相模型合成完整的海底扇沉积微相模型。模拟结果表明, 应用分步相模拟建立的海底扇沉积相模型更接近地质认识, 提高了沉积相的模拟精度。

Construc tion o f sedim entary m icro - facie m ode ls of
subm ar ine fan can no t on ly predict the spatia l d istribution

can only be utilized w ithin a lim ited scope, there is no t a

Firstly, facie transition sim ulation is screened to construct the
sedim en tary sub - fac ies model o f subm arine fan. Then,
ob ject based me thod and K rig ing indictor are utilized to
construct the sedim entary m icro- fac ie o fm id- fan and low er
