摘　　要：基于渤海南部中轻质油田——S油田油水两相渗流规律,建立了不同含水阶段、不同储层厚度、不同流度条件下的单井合理产能图版,筛选油井日产油量低于合理产能20%的井作为挖潜对象。然后,结合筛选出单井的地下、井筒、地面实际情况,一井一策、针对性提出治理方案,并将“合理产能”作为评价措施效果的标准。2019年S油田通过多种工艺手段共治理油井13口,平均单井日增油达到45 m^(3),效果显著,为同类油田增产挖潜提供了借鉴。Based on the seepage laws of oil-water two-phase flow in N oilfield,a medium light oil field in the south of Bohai Oilfield,the reasonable productivity chart of single well under different water cut stages,different reservoir thickness and different mobility conditions is established,and the wells whose daily oil production is less than 20%of the reasonable productivity are selected as the potential tapping wells.Then,combined with the actual situation of the underground,well bore and ground facilities of single well,the treatment scheme is proposed according to the actual situation of each well,and“reasonable productivity”is taken as the evaluation criterion of whether the measures achieve the effect.In 2019,13 wells in S oilfield were treated by various technological means.The average daily oil increment of a single well reached 45 m^(3),and the effect was remarkable,which provided a reference for other similar oilfields to increasing production measures.
