摘要
随着南海惠州A油田进入"双特高"(特高含水、特高采出程度)开发期,剩余油分布呈现"高度分散、局部相对富集"的特点。为此,综合运用3.5维地震技术(时移地震技术),通过岩石物理分析、叠前地震资料处理、油藏动、静态等方面的研究,根据地震振幅差异与油井生产动态的关系预测剩余油分布。研究成果应用于油田开发调整方案的实施,开发调整井实钻结果表明该方法有助于油田后期剩余油的挖潜。
As development goes on,the Huizhou A oilfield in the South China Sea shows characteristics of extra-high water cut and extra-high recovery,so that the remaining oil is globally scattered and locally enriched.After conducting 3.5 Dand T-L seismic survey based on dual-azimuth high-quality3 D seismic technology,and carrying out rock physical analysis,prestack time-lapse data processing and spatial dynamic production information interpretation,the distribution of the remaining oil was investigated based on the relationship of seismic amplitude and dynamic information of reservoir production during the later development stage of the oilfield.The seismic result has been applied to update the pressure-depleting development plan in the Huizhou A oilfield.New wells show high recovery and help to produce the remaining oil.
