　　实验室测得的相对渗透率曲线仅代表了井点取心段的流动特征，往往与实际生产特征不符，需要在数值模拟历史拟合阶段进行校正，该过程繁琐且耗时耗力。文中提出了一种利用非线性优化理论校正相对渗透率曲线的方法。该方法假定油水相对渗透率呈广泛使用的指数函数关系，通过理论计算与实际含水－采出曲线进行拟合，确定相对渗透率曲线关系式。该方法需要参数少，计算方便、速度快。通过吐哈油田温西3区块历史拟合后的相对渗透率曲线验证，校正后的相对渗透率曲线与历史拟合相对渗透率曲线更吻合，表明校正方法是可行的。校正后的相对渗透率曲线具有较好的代表性，形态良好，克服了曲线上凸。通过新的油水相对渗透曲线计算的理论含水率－采出程度曲线与实际曲线拟合较好，符合实际生产的需要，具有一定的理论和应用价值。

The relative permeability curves from laboratory measurement only represent the flow behavious of core sample and commonly do not accord with the real flow behaviors ,thus they need to be corrected through history matching .How-ever ,the process of history matching is time-consuming and labor-intensive .The current study introduces a new method to correct the relative permeability curves based on the nonlinear optimization theory and accurate experimental endpoint . Based on the assumption that the relative permeability satisfies the exponential function ,the theoretical water cut-recovery curve (fw-R) is fitted to the actual fw-R curve to obtain relative permeability curves .The new method requires fewer pa-rameters and is simple and faster .Application of the new method to Turpan-Hami Oilfield WENXI 3 block shows that the the corrected relative permeability curves fit better with the calculated relative permeability through history matching ,in-dicating this correction method is feasible .The corrected relative permeability curves are representative and in good shape .The theoretical water cut-recovery curves obtained by using the new method are in good accordance with the real curves.
