Log-F acies Geological Analysis in Shinan Area, Junggar Basin

Abstract

Abstract: Rapid petroleum sci-tech development nowadays allows well logging geology more and more to participate in analyzing and finding out geologic prospecting targets. The grain size, sandbody, petrophysical property, hydrodynamic intensity and distribution, well log shape and vertical sequence variation are studied. It is suggested that the sedimentary facies of Jurassic Toutunhe formation (J2), the major payzone in Shinan area, belongs to a braided river island deposit with paleocurrent directions of east-south and west-south. The spatial distribution of depositional sandbody is described in this paper. Applying diplogs to reconstruction and interprelation of depositional structural sequences could be to ascertain paleogeographic events or prospecting targets for advantages of well logging.

Key words: diplog, sedimentary lithofacies, log facies, grain size, sand body
