大路沟二区特低渗透油藏测井响应特征研究

Logging response characteristics of ultra-low permeability reservoir in Dalugou area

主要根据水驱油田油水层、物性变化以及水淹层的变化规律,通过对各种测井方法的分析,总结不同油藏类型的水淹模式,掌握特低渗储层不同水淹程度典型特征,明确水淹前后储层岩性、物性、电性及含油饱和度等的变化规律。

In this paper,according to the oil and water layer,physical property change and the variation law of water flooded layer in water drive oil field.through the analysis of various logging methods,the water flooded mode of different reservoir types is summarized,the typical characteristics of different water flooded degree of special low permeability reservoir are mastered,and the lithology,physical property,electricity and oil saturation of the reservoir before and after water flooding are clearly defined.
