Abstract

The significance increase of recoverable oil reserves in reservoirs of deep horizons requires more detailed study of their formation conditions. Granulometric and mineralogical investigations of terrigenous sediments allow obtaining the basic ideas on their sedimentation conditions. In this case the combination of the existing methods enables to address some issues of facies analysis. The integrated investigations of the horizons JK2-5 of Tumensk formation in Em-Egovskoe area, Krasnoleninskoe field (208 samples) have been performed. Based on granulometric and mineralogical studies, the authors made the conclusion that the sediments studied had been formed within the estuary. The results of the study show that the sedimentation conditions may be different under the same dynamic accumulation conditions and similar particle granulometric distributions. The efficiency of facies prediction can be enhanced only through the integrated analysis.
