海拉尔盆地贝尔凹陷贝301区块南屯组沉积微相研究

The sedimentary microfacies study of Nantun in bei 301 block in Bei'er depression of Hailar Basin

依据岩心、地震、测井和录井资料,应用测井理论和沉积学的原理和方法,查明了海拉尔盆地贝尔凹陷贝301区块南屯组沉积微相特征。结果表明,贝尔凹陷贝301区块南屯组的沉积微相类型主要为扇三角洲前缘的水下分流河道,水下分流河道间,河口坝,席状砂。

Based on core, seismic, logging and logging data, application the logging theory and the principles and methods of sedimentology, to identify The sedimentary microfacies study of Nantun in bei 301 block in Bei＇er depression of Hailar Basin. The results showed that the sedimentary microfacies types mainly Subaqueous distributary channel ,inter of Subaqueous distributary channel , the mouth bar, sand sheet of Fan--delta front.
