硼中子寿命测井在特殊岩性储集层的应用

An Applied Study on Boron-Neutro-Lifetime Logging for Formations with Special Lithology.

对硼中子寿命测井解释原理及其适应性进行分析认为 ,该方法可以在裂缝性火山岩、砾岩、非均质性极强的砂岩地层中应用。在二连油田阿北安山岩、蒙古林砾岩等油藏进行的现场实验 ,取得了较好的经济效益 ,拓展了硼中子寿命测井的应用范围 ,为特殊岩性寻找剩余油分布提供了手段。

Based on the analysis of theory and adaptability, it is claimed that a boron neutron lifetime logging can be used for formations with special lithology such as fractured lava, conglomerate and strong heterogeneous sandstone. In Erlian oil field, the application domain of the logging are enlarged by locale experiments performed at Abei andesite and Menggulin conglomerate reservoirs, and preferable economical benefit is acquired. That may offer new methods to determine residual oil distribution in formations with special lithology.
