摘　　要：根据准噶尔盆地石南油田石南21井区中侏罗统头屯河组高钙砂岩的宏观和微观分布特征,分析了高钙砂岩的成因及其意义,明确指出它具有等时性和等深性,可作为一个重要标志层对头屯河组头二段(J2t2)砂层组进行细分与对比,并提出了该砂层组的细分方案,为油藏精细描述和油田开发方案的编制奠定了地质基础。Based on the macro- and micro-distribution characteristics of high lime sandstone of Jurassic Toutunhe formation in Shinan-21 Wellblock, Shinan oilfield, Junggar basin, this paper presents the origin and significance of the high lime sandstone, and points out that its distinct isochronous and isopath properties may be regarded as an important horizon marker for subdivision and correlation of J2t2 sand layer of Toutunhe formation. The subdivision concept proposed herein could be as a guide for detailed reservoir characterization and further development scheme preparation of this oilfield.
