摘　　要：薄互储层合采且层间非均质较强的油藏,各小层采出程度不仅受储层物性的影响,而且受单井小层井控地质储量的影响。综合考虑上述产能影响因素,针对天然能量开采的油藏,提出了一种新的产量劈分方法,简称KNK方法。该方法劈分结果更接近实测产液剖面,尤其对层间差异较大的薄互储层合采井,更符合油藏实际地质状况,具有较强的适用性。When the thin interbedded reservoir adopts commingling production and the interlayer heterogeneity is strong, the recovery percent is not only influenced by the reservoir property but also by the oiliness and well control geological reserves of each layer. Based on above influence factors of productivity, the paper raised a new production split method which named KNK method. The results of the new production split method is much closer to the Liquid Production Profile and much closer to the geological conditions, especially for the comingled producing wells which drived on thin interbedded sandstone heterogeneous reservoir. The new method is feasible, applicable and maneuverable.
