研究区自开发以来尚未进行系统的地质方面的研究,具有注水开发时间长、注水效果较差、低产井较多、非均质性强、地层结构复杂等特点,但地质储量较大、采收率低,有很大的开发潜力。针对研究区所存在的这类问题,进行深入的油藏储层非均质性研究,以达到对储层更深入了解的目的,为其他区块同类油藏开发提供技术支持。
Since the development of the study area, no systematic geological research has been carried out, which has the characteristics of long time of water injection development, poor water injection effect, more low-yielding wells, strong heterogeneity and complex stratigraphic structure. However, with large geological reserves and recovery Low rate, there is great potential for development. In view of the problems existing in the study area, the in-depth research on reservoir heterogeneity is carried out in order to reach a deeper understanding of the reservoir and provide technical support for the development of similar reservoirs in other blocks.
