摘　　要："十三五"期间,大庆油田二类油层一次上返开发将全面结束,二次上(下)返开发存在着层序及方式选择的问题。为确定二类油层上(下)返开发方式,以喇嘛甸油田南中东二区为例开展研究。技术上从区块静动态资料入手,利用统计方法分析,落实上(下)返层系潜力,确定葡Ⅱ1—高Ⅰ5为下步开发层段;经济上利用大数据理论,建立系统模型,创建钻新井与利用一套井网开发方式选择图版,确定了南中东二区上(下)返开发方式。研究结果表明,油价50美元/桶及以上时,南中东二区葡Ⅱ1—高Ⅰ5层系应采用新钻井方式开发。该方法为二类油层区块有效开发提供了技术支持,对层状砂岩油藏开发具有一定的指导意义。During the 13th national five-year plan,Class Ⅱ oil reservoirs of Daqing Oilfield first upward development will be fully completed,the problems of the sequence and mode selections in the second upward(downward）layer development need to settle. In order to determine their return development ways,Middle East-2 of Block South in Lamadian Oilfield was taken as the studying example. In technical aspect,from the perspective of the blocks in the static and dynamic data,with the help of the statistical method,the potentials of the returned series were analyzed and ensured,Interval PⅡ1-GⅠ5 were determined to be developed next; economically,using the theory of big data,the systematical model was established,the choosing chart of the development modes was established between the new drilled wells and one set of the well pattern selection,and moreover the developing modes of the returned layers in Middle East-2 of Block South were determined. The research achievements show that when the oil price is up to $ 50/barrel or above,the development of the new well drilling shall be used for these oil reservoirs in the interval. The method has provided the technical support for the effective development of Class Ⅱ oil reservoirs inthe block and possesses a certain guiding significance for the development of the layered sandstone oil reservoir.
