摘要
大芦湖油田樊107块为扇三角州前缘滑塌浊积形成的岩性油藏,具有埋藏深、渗透率低、油水关系复杂等特点。通过合理选择注采井网、恰当选择注水及层间、井间的接替时机,以及整体压裂改造、控制注采比注水等技术措施,实现了特低渗透油藏的成功开发。樊107块注水开发取得了良好效果:采出程度高、含水率低、剩余可采储量的采油速度高、地下存水率高。主要开发指标高于同类型油田,可为类似油藏的开发提供借鉴作用。
Block Fan 107 of Daluhu Oilfield, which is formed by the slump deposits in front of the fan delta, is a lithologic oil pool with large buried depth, low permeability and complex oil-water contacts. It is successfully developed in the ultra low permeability reseavoir through the reasonable selection of injection-production patterns, flooding, interformational and interwell replacing time, integral fracturing and controlling injection-production ratio. The flood development has got a good effect in Block Fan 107, which shows a high recovery percent of reserves, low water cut, high oil production rate of residual recoverable reserves, high water storage rate in underground. The development indexes are better than that of same type of oilfield and it can be used as a reference for the deveolpment of similar reservoirs.
