OUTCROP STUDY ON CONFIGURATIONS AND RESERVOIR HETEROGENETTY IN MEANDERING CHANNEL SANDBODY- An Example from Outcrop Sandbody of Yanan Formation in Northeastern Erdos Basin

Abstract

Abstract: This paper dissected the configuration and reservoir heterogeneity characteristics in meandering channel sandbody in Zhaoshiyao on the scale of macroscope,mesoscope and microscope. Based on the realistical description of the cliff and the observation of space geometric shape, types and characteristics of genetic facies and their interrelation of sandbody, six levels of interfaces, twelve types of reservoir lithofacies and four types of barrier beds were distinguished, their sedimentation and distribution characteristics were studied. Hence an important basis for developing the quantitative reservoir model is provided.

Key words: Erdos basin, Channel sand, Structure, Heterogeneity, Outcrop Study
