牛心坨油田储层特征及其定量模拟

Reservoir Characteristics and Quantitative Simulation of Niuxintuo Oilfield

在等时层序地层格架的基础上 ,对辽河盆地牛心坨油田牛心坨油层的 8个层序进行了储层特征分析及地质统计学定量模拟 ,并结合沉积相展布特征对其中的层序 进行详细分析 ,建立了 0°,4 5°和 1 3 5°三个方向上的变差函数模型。模拟结果表明 ,层序 的储层砂体在 1 3 5°方向最为连续 ,其次为 0°方向 ,4 5°方向的砂体连续性最差。这与沉积相分析结果完全一致。

On the basis of an isochronous sequence stratigraphic framework, an analysis on reservoir characteristics and a geologically statistic quantitative simulation of 8 sequences are performed in the Niuxintuo reservoir of Niuxintuo oilfield in Liaohe basin In combination with the through going feature of sedimentary facies, sequence V among the 8 sequences is analyzed in detail A variation functional model is established in the directions of 0°,45° and 135° The result of simulation shows that the continuity of the sandbody in V is the best at 135°,the next at 0° and the worst at 45°, which is consistent with the analysis result of sedimentary facies
