徐深气田开发营城组砾岩、火山岩储层,储层致密且非均质性强,气藏类型复杂,试井曲线形态各异,需采用不同的模型进行解释。本文结合静动态资料、压裂作业、测试工艺,建立起3种井模型、3种储层模型及边界模型组合的试井解释模型,对徐深气田投入试采以来所有井的压力恢复试井资料进行解释,并对井模型和储层模型进行分类总结,掌握气井及地层基本参数,以实现徐深气田的合理高效开发。
The Yushen gas field develops Yingcheng Formation conglomerate and volcanic reservoirs. The reservoirs are dense and highly heterogeneous. The types of gas reservoirs are complex and the shapes of well test curves are different. Different models need to be used for interpretation. Based on the static and dynamic data, fracturing operation and testing technology, a well testing interpretation model of three well models, three reservoir models and boundary model combination is established. Data are interpreted, and the well model and reservoir model are classified and summarized, and the basic parameters of gas well and formation are grasped so as to realize the rational and efficient development of Xushen gas field.
