Abstract

China is a country with rich oil reserves. With the development of the reservoir, the proportion of fault block reservoir (hereinafter referred to as FBR) discovery increases gradually. At present, FBR has occupied a considerable proportion of China’s oil reserves. Zhongyuan Oilfield is mainly composed of complex FBR. FBR has unique characteristics, such as small fault block and complex geological structure, which will greatly increase the difficulty of development in the middle and late development. Therefore, we must comprehensively adjust and tap the potential of FBR, which will achieve long-term stable production in the middle and late stage of fault block oilfield. Therefore, based on the characteristics and classification of FBR, this paper analyzes the development status in the middle and late stage. Then, according to the characteristics of fault block oilfield in the middle and late stage, this paper puts forward some comprehensive adjustment technical measures, which will better adapt to the reasonable development mode of FBR in the middle and late stage.
