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。
The Hutubi gas field is a condensate gas reservoir with edge water. The experience of similar gas reservoirs shows that if the gas production rate is unreasonable, it may lead to early seepage of gas reservoirs and severely restrict the improvement of final oil recovery rate. Therefore, how Determine a reasonable gas production rate, the working system is the key to the development of gas reservoirs. Through further research on the dynamic monitoring data of Hutubi gas field in recent years, dividing the pressure system of gas reservoir and combining with the development dynamics, the productivity distribution characteristics of gas reservoir and the degree of formation water activity are analyzed. Using the means of production, Reserves were verified to determine a reasonable gas production rate and work system, to provide a scientific basis for rational development.
