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.
