摘　　要：大庆喇萨杏油田过渡带地区已进入特高含水开发期,不同区块的地质特征与开发现状差异明显。为了系统评价各区块开发效果,寻找潜力调整区块,根据地质与开发2类指标建立了多指标评价体系,利用模糊综合评判方法对地质与开发指标进行了分级评价与分类。按照地质与开发评价结果匹配原则,确定了下一步需要进行开发调整的潜力区块。根据过渡带地区存在的主要问题制定了包含6类开发调整方式的流程,确定了层系重组、井网加密和层系互补的界限值大小,最终给出了潜力区块的具体调整方式。现场试验取得了较好的效果,为大庆油田特高含水期过渡带地区挖潜提供了依据。The transition zone of Daqing Oilfield has entered the extra-high water-cut stage and geological features and developing status in each block are obviously different. In order to evaluate development effect of each block systematically to find potential region for adjustment, a multi-object assessment system is established from the aspects of geology and development, the geological and developing indexes are evaluated and classified with comprehensive fuzzy evaluation method. According to the matching principle between geology and development evaluation results, the potential blocks that need to be adjusted in the next step are determined. In allusion to the problems in transitional zone, a process consisting of six types of development and adjustment methods is developed. The size of limited values for strata reconstruction, well pattern infill and strata complement is determined, eventually the adjustment modes of potential blocks are provided,good results are obtained in field application, it provides a basis for potential tapping in the transitional zones at extra-high water-cut stage in Daqing Oilfield.
