摘要： 通过对石南地区粒度、砂体，物性的研究以及对水动力强度、测井曲线形态及垂向序列变化关系的研究,确定石南地区主力油层即侏罗系头屯河组(Jt)沉积相为辫状河心滩沉积,古水流方向为东南向和西南向。通过测井沉积相的分析,描述了沉积砂体的空间展布。利用倾角测井资料进行沉积构造序列的重建和解释并确定沉积古地理标志，体现了测井的巨大优势。

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
