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 isochronous sequence stratigraphic framework, reservoir characteristics and geostatistics quantitative simulation of 8 sequences of Niuxintuo reservoir in Niuxintuo Oilfield of Liaohe Basin were carried out. Based on the distribution characteristics of sedimentary facies, , The variogram model of three directions of 0 °, 45 ° and 1 3 5 ° is established. The simulation results show that the sequence of the reservoir sandstone is most continuous in the direction of 1 35 °, followed by the direction of 0 °, and the sand body in the direction of 45 ° has the worst continuity. This is consistent with the sedimentary facies analysis.
