摘　　要：坪北油田进入细分层注水开发阶段,注水注不进、注水不见效等情况越来越突出,为解决坪北油田层间矛盾,以长4+5和长6油组为主要研究对象,明确了研究区的物源方向,开展岩性与测井曲线对比,确定区域标志层与各地层界面间的关系,识别出4个小层对比标志层,厘定全区小层划分标准,完成了全区的小层对比划分。首次统一各采矿区的分层标准,实现了坪北油田全区连片统层。As Pingbei oilfield falls into the fine-layer water injection phase,such scenarios are becoming outstanding as water fails to be injected and water injection does not work.In order to overcome the obstacle between layers in Pingbei oilfield,taking Chang 4+5 and Chang 6 oil groups as the main research objects,we defined the source orientation of the study area,performed the correlation of lithologies and well logs,determined the relationship between the regional marker layer and the formation interface,identified 4 fine regional marker layers,defined the standard for division of the whole regions fine layers,and completed the correlated division of the regions fine layers.For the first time,the layering standard for each area was unified,covering the whole area of Pingbei oilfield.
