摘　　要：MQ油田低阻油层主要是因为该区储层夹有薄泥岩层,导致油层电阻率偏低,常规测井解释很难将油层、水层和干层区分开,针对这种现象,采用先进的软件包,利用多方程和多参数综合解释新技术,很好地分清油水层,找到了识别低电阻率油层的有效方法,确定了该油田油层、水层和干层的识别标准。The low resisitivity layers in MQ oilfield are the result of the thin mudstone layers interbeded between reservoirs. These interlayers lower the resistivity of oil layers, thus the identification of oil layer, water layers and dry layers is difficult on conventional logs. New integrated interpretation techniques with multi - equation and multi -parameter are used to accurately discriminate oil and water layers. This paper presents several effective methods for identification of low resistivity layers and the criteria for i-dentification of oil layer, water layer and dry layers.
