摘　　要：奈曼油田2016-2018分层系开发之后,主要分为九上Ⅰ+Ⅱ、九上Ⅲ和九下段三套层系开发,从前期的分析效果看,奈曼油田的油藏边界基本已认识清楚,扩边增储的潜力已不大,作为整装注水油田,注好水是奈曼油田保持稳产的基础,但由于奈曼油田含油井段长,随着开发的深入,油井生产井段较长,为保持注采对应,水井注水井段也越来越长,目前奈曼油田平均单井注水厚度为70.6m,平均单井注水层数为2.5层,另外由于奈曼所有投产的油井均需压裂,地层又发育天然裂缝,因此受人工裂缝和天然裂缝的影响,奈曼油田目前还存在着水淹,水窜严重,水驱方向性强,受效单一,注水井吸水动用不均匀等问题,现阶段仅依靠常规水井措施已无法改善注水开发效果,主要结合目前存在的问题进行分析并给出调整建议。After the development of the layered system in Naiman Oilfield in 2016-2018,it is mainly divided into three sets of layer development,Jiushang I+Ⅱ,Jiushang III,and Jiushang section.From the analysis results of the previous period,the reservoir boundary of the Naiman oilfield is basically It has been clearly understood that the potential for expanding the edge and increasing reserves is not great.As a water injection field,the good water injection is the basis for the Naiman oilfield to maintain stable production.However,due to the length of the oil-bearing well in the Naiman oilfield,with the development of the oil well The well section is longer.In order to maintain the injection-production correspondence,the well injection section is getting longer and longer.At present,the average single well injection thickness in the Naiman Oilfield is 70.6 meters,and the average single well injection layer is 2.5 layers.All oil wells need to be fractured,and natural fractures are developed in the formation.Therefore,under the influence of artificial fractures and natural fractures,the Naiman Oilfield still has flooding,serious water channeling,strong water flooding,single effect,single injection well Due to uneven utilization and other problems,at this stage,relying on conventional well measures alone cannot improve the effect of water injection development.This article will analyze the existing problems and give suggestions for the next adjustment of the Naiman Oilfield.
