摘　　要：海上油田群联合开发涉及因素众多,高含水阶段往往因受到生产设施能力的约束而难以发挥最大产能,因此基于现有设施能力在有限时间内获得最大产油量和最少产水量是这类油田群急需解决的问题。针对这一难题,通过综合考虑海上油田群生产各环节,基于广适水驱特征曲线建立了油田群单井液量优化模型,通过惩罚函数法求解得到单井最优日产液量,实现了油田群级别的单井液量优化。应用实例计算表明,液量优化后油田群的年产油量得到显著增加,含水率明显下降,降水增油效果显著,同时实现了油田群各生产因素对原油产量影响的定量表征。该方法基于平台-井筒-油藏一体化统筹考虑,所需数据简单易取,计算结果可靠,现场实施方便,具有投入低、收益高的优点,在海上油田具有广泛的应用前景。Joint development of offshore oilfield groups involves multiple influencing factors and the full produc-tion capacity is inhibited by production facility in high water cut stage. Aiming at the maximum oil and mini-mum water production based on existing facility capacity, an optimization model for single well in oilfield groups is established based on comprehensive consideration of all production factors of the oilfield group and the eurytopic water-drive curve. The optimal daily liquid production of single well is obtained with the penalty function method, and the liquid production optimization of single well of the oilfield group level is achieved. The case application and calculation results show that the yearly oil production increases and water cut decrea-ses after optimization with this model, while the quantitative characterization of oil production based on multi-ple production factors of the oil fil^d group is realized. Based on comprehensive consideration of platform-well-bore-reservoir, the proposed method is featured with accessible data, reliable calculation results, convenient implementation and low cost with high profit, showing a broad application prospect in offshore oilfield.
