利用矿场资料预测剩余油分布

根据平面径向流公式和物质平衡方程推导出可代表整个油藏的油水相对渗透率比值,以及含水饱和度与矿场生产资料的关系,从而确定二者之间的相关关系;根据水分流量公式,推导出含水饱和度与含水的关系,进而计算单井剩余油饱和度,预测整个油藏或单元的剩余油饱和度分布规律,为下一步调整提供可靠的依据。在实际应用过程中,取得了较好的效果。

REMAINING OIL DISTRIBUTION PREDICTION BASED ON OIL FIELD DATA

Based on the planar radial flow equations and material balance equations, the relational expression between water cut and water saturation was derived from oil field data? and from the theory of reservoir engineering and percolate mechanics, and then the relationships between the water saturation and the water was derived. According to the water-oil discharge equation,the model may predict remaining oil saturation of single-well and the remaining oil distribution in the whole reservoir or unit.It is proved the reliable supports for the next development.
