摘要
尕斯库勒N1-N12油藏为低渗透砂岩油藏,经过了20多年的开发,目前已进入中高含水期,调整和挖潜难度增大。其主要特征是天然能量低,地层能量难以得到保持,储层非均质性强,层间干扰严重,注水利用率差。利用油藏工程方法对其开发特征进行研究,分析其存在的主要问题,并针对其潜力提出了采用合理的井网形式,合理加密井网,调整注采系统,开展老井措施等综合调整策略。现场生产实践证明,应用效果良好,所取得的研究成果对油田开发具有较强的指导意义。
Gasikule N1-N12 Oilfield is low permeability sandstone reservoir,it has been under development for more than 20 years.At present,it enteredin to mid or high water cut stage,adjustment and tapping the potential were difficulty.It has following characteristics:low nature energy;formation energy is difficult to be maintained;strong reservoir heterogeneity;serious interlayer interference and inefficient water injection.By studying the current status of exploitation of Reservoir by the approach of petroleum reservoir engineering and analyzing the main problems,the paper proposed a reasonable well pattern,adjustment injection system,to carry out old wells measures and other comprehensive adjustment strategy to improve development effect.It was proved that the practical effect is good and a guidance is provided for oilfield development.
