摘要
海上油田注水井层间跨度大,层间关系复杂,最高允许注入压力计算方法具有不确定性,这些不利因素给注水井多层配注安全带来困难,目前尚未有一套成熟的监测方法与手段。基于海上注水井注入压力与流量监测,提出一套注水井安全监测方法及实施方案。目前该方法已在海上油田实施应用,在保障注水井注入安全的前提下提高了注水井的注入量,进而实现了油田的配注指标。
For water flooding offshore oilfield, the interlayer span is large, interlayer relationship is complex and the calculation method for maximum al-lowable injection pressure has uncertainty, which are unfavorable to monitor the safety of muhilayer injec- tion allocation. Up to now, there is not a set of ma-ture methods and measures to monitor the injectors. This paper presents a method and the implementa-tion plan to monitor the safety of water injection based on the injection pressure and flow rate monito-ring in offshore water injectors. This method has been applied to improve the flow rate of the injectors under the premise of keeping the injector safe.
