摘要
塔中油田CⅢ1是上有凝析气顶、下有边底水的块状油气藏 ,从单井试采及上产、降压高产、全面注水开发等 3个不同阶段的开发特征入手 ,分析影响开发效果的各种因素 ,研究了该油藏的地层压力变化取决于采油速度 ;生产气油比受地层压力影响明显 ;地层能量消耗造成地层流压下降等特征 ,同时提出保持和恢复地层压力的合理注水量、合理的采油速度和合理开发的地层压力界限值。
Tazhong Oil Field CIII1 Reservoir is a fault block reservoir with condensate gas cap in the upper part and side bottom water in the lower part. This paper studies the development characteristic of 3 stages of single well production test and producing, decreasing pressure with high production and overall water injection development, and analyzes the factors which affect the development effect. It shows that the formation pressure change of this reservoir depends on the production rate, the production gas oil ratio is obviously affected by formation pressure, and the formation energy consumption decreases the formation flow pressure. It proposes a formation pressure limit value for the preservation and restoration of formation pressure and reasonable water injection rate, production rate and development. This study has referential significance for the development of oil and gas reservoirs of the same type.
