| 摘 要： | 在对低渗透凝析气藏采取压裂措施时,压裂后的返排过程影响到液锁对地层的伤害程度。建立了凝析气藏压裂后返排模型和凝析气藏压裂后的产能模型,利用该返排模型可以确定出压裂返排过程中裂缝和地层内的压力分布,结合产能模型可以确定出不同返排速度时两种液锁现象对产能的影响。同时结合实例分析了返排速度对产能的影响,为优化凝析气藏压裂后的返排过程提供了理论依据。

| Abstract: | The speed of flowback during fracturing influences the damage of liquid invading when taking a fracture measure to a low permeability condensate reservoir. This paper first establishes the models of flowback and production after fracturing and educes the pressure distribution in the fracture and formation making use of the two models. With theproduction model, this paper makes sure of the influences of two kinds of liquid invading to the production when there are different speeds of flowback. Meanwhile this paper refers to instances to analyze how the flowback speed affects the production and provides the basis for valid flowback speed. |
