摘要:

运用无机地球化学元素示踪方法,对储层方解石胶结物中的MnO含量变化趋势进行了分析,就准噶尔盆地莫索湾-莫北地区的油气运移方向开展比较系统地研究,揭示了盆1井西凹陷、昌吉凹陷和东道海子北凹陷的油源对该区都有贡献,但在油源组成、充注范围和强度上有所不同,可以划分出3个成藏体系:盆1井西凹陷-东环带、昌吉凹陷-莫索湾、东道海子北凹陷北坡成藏体系,并认为莫索湾凸起的南东翼和东道海子北凹陷的西北斜坡区是有利探勘区域.

Abstract:

The inorganic geochemical element tracing approach is adopted in the analysis of changing trends of the MnO content in the calcite cements of reservoirs and the systematic study of hydrocarbon migration direction in the Mosuowan-Mobei area of the Junggar Basin.The results show that the source rocks in the Well Pen-1 west sag,Changji sag,and Ddhzb sag,all have contributed to the pools in the study area,but they vary in the composition of oil,charging ranges,and intensities.Three plays are recognized in the study area,including Well Pen-1 west sag-east loop belt,Changji sag-Mosuowan uplift,and northern slope of Ddhzb sag.The southeastern flank of Musuowan uplift and the northwestern slope zone of Ddhzb sag are prospective targets for exploration.

Key words: calcite cement, MnO, element tracing approach, inorganic geochemistry, play, hydrocarbon migration direction, Mosuowan-Mobei area, Junggar Basin
