重力浊积流油藏具有非均质性强、连通差、物性差的特点,常规的面积注采井网不能适应储层非均质性强的特点,平面、纵向水驱动用差,影响水驱开发效果。根据油藏地质体特征结合试注开发的注水特征,采用新型的相控注水原则调整井别,对主力相带注水,高注低采、厚注薄采,实现平行物源的线性注水,能够实现重力浊积流油藏有效注水开发,该井网在辽河油田L35块投入应用后取得了较好的开发效果。
The gravity turbidite reservoir has the characteristics of strong heterogeneity, poor connectivity and poor physical properties. Conventional area injection well pattern can not adapt to the characteristics of reservoir heterogeneity, Drive development effect. According to the characteristics of reservoir geology and the characteristics of water injection developed by the pilot project, a new type of phased water injection principle is used to adjust the well water injection. The main injection water injection, high injection low injection, thick injection thin injection, parallel injection of water, The gravity nebulizer flow reservoir is effectively flooded and developed. The well pattern has achieved good development results after the L35 block of Liaohe Oilfield was put into operation.
