摘　　要：苏北盆地低对比度油层主要是由于低电阻、物性差异及层薄所致。针对不同特征及成因的低对比度油层,提出了求取束缚水饱和度、利用神经网络判别及建立多参数判别模型等多种识别方法,有效提高了低对比度油层识别的可靠性和准确性,并在生产中取得了明显的效果。In Subei Basin,low-contrast reservoirs were mainly induced due to the low resistance,petrophysical differences and the thick reservoirs.According to the different characteristics and the reasons of the low-contrast reservoirs,several kinds of recognition methods were established,such as calculating bond water saturation,using neural network discrimination and establishing multi-parameter models.Those effectively improve the accuracy of low-contrast reservoirs,an obvious effect is obtained in production.
