Abstract: On the basis of previous studies, the lithology, physical properties, electrical properties and oilbearing characteristics of Chang6 reservoir in this area are analyzed and studied. Further, the Chang 6 reservoirs in this area are divided into four types: pay bed (oilwater layer), waterproducing layer, mixed zone (mixed zone of pay bed and water producing) and dry layer. Then, the fluid identification standard for the Chang6 reservoirs of the target area is established based on the logging standardization. It is proved that the standard is effective by examples, which provides powerful technical support for identifying pay bed quickly and accurately in this area. The results of this study have important guiding significance.

摘要： 对鄂尔多斯盆地黄陵上畛子地区延长组长6油层组储层岩性、物性、电性与含油性特征及其关系进行了深入分析和研究，并进一步将该区长6储层分为产油层（油水同层）、产水层、混合区（产油、产水层混合区）以及干层四类，基于测井标准化，建立了目标区长6储层流体识别标准,经实例验证有效，为该地区快速准确识别产油层提供了有力技术支撑，具有重要的指导意义。
