摘　　要：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。Chang2 reservoir in Tangshan oilfield has the characteristics of long water injection development time, poor injection effect, strong heterogeneity and complex stratigraphic structure, but it has great potential for development. In this paper, the heterogeneity of Chang2 reservoir in Tangshan oilfield was studied in order to achieve a more in-depth understanding of the reservoir, which could provide technical support for development of similar reservoirs.
