动态监测技术在呼图壁气田的应用

呼图壁气田是存在边底水的凝析气藏,同类气藏开发的经验表明,如果采气速度不合理,可能导致气藏提前见水,严重制约最终采收率的提高,因此,如何确定合理的采气速度、工作制度是气藏开发的关键。通过对呼图壁气田近年来动态监测资料进行深入研究,划分气藏压力系统,并结合开发动态,对气藏的产能分布特征、地层水活跃程度进行了分析,利用生产资料,对气藏动态储量进行了核实,确定出了合理的采气速度及工作制度,为合理开发提供科学的依据。

Application of Dynamic Monitoring Technique in Hutubi Gas Fieldc

Hutubi Gas Field is a condensate reservoir with edge-bottom water, the experience of similar gas reservoir production shows that if gas production velocity is improper, water breakthrough ahead of time is possibly caused, by which ultimate gas recovery is constrained. Therefore how to determine rational gas production velocity and work system is the key of its production. The pressure system of the gas reservoir is classified by deeply studying the dynamic monitoring data of recent years, and in combination with production performance, the characteristics of its productivity and level of formation water activity are analyzed. Production data are used to check its dynamic reserves, determine rational production velocity and work system for providing basis for rational production.
