摘要： 从煤系地层沉积序列特征、沉积环境分析入手,探讨了准噶尔盆地下侏罗统八道湾组的聚煤环境,其中,可容空间变化速率与泥炭沉积速率保持平衡关系的持续时间,是形成稳定分布煤层的主控因素。认为该煤层具有等时性,可作为层序边界。建立了侏罗系八道湾组层序地层模式,为高精度地层对比和岩性油气藏的勘探提供了依据。

Abstract: From the analysis of sedimentary sequence of coal-bearing strata and sedimentary environment, the influencing factors of coal accumulation of Lower Jurassic Badaowan formation in Junggar basin are discussed. It is shown that the balance-standing time/period between the rate of accommodation changes and the rate of peat deposition is a major controlling factor to form a stable distribution of the coal seam. So the isochronous distribution of the coal seam can be as a sequence boundary. This paper presents the model for sequence stratigraphy of the Badaowan formation, which could be as a guide for high-precision sequence stratigraphic correlation and lithologic reservoir exploration in this area.

Key words: Junggar basin, Dinan swell, Badaowan formation, coal-bearing strata, coal measures, sedimentary environment, sequence stratigraphy
