摘要
阐述了储层动态描述技术原理。结合气井生产与不稳定测试资料对涩北气田进行了储层动态分析,研究了储层动态模型,确定了地层参数,指出涩北气田主要存在均质地层、径向复合地层与多层窜流三种地层模型,认为径向复合地层与多层窜流地层均是气井多层合采的动态反映。为了研究储层动态模型随时间的变化,将储层动态描述技术应用于单井多次测试。分析得到,在长期的生产过程中,气藏的地层模型、储层参数并没有发生明显变化。储层动态描述确定的地层模型在产能计算与产能预测、气井生产预测等方面有着重要的作用,比静态地质模型更具实际意义。
The tech principle of reservoir performance description is expounded. Combing with production in gas well and data of transient well testing, reservoir performance of Sebei oil field is analyzed, reservoir performance model is studied and formation factors are determined which point out that there are primarily three types of formation models in Sebei gas field, such as homogeneous one, radial composition one and multi-layer breakthrough flow. it is thought that radial composition and multi-layer breakthrough flow formation are performance reactions of multi-layer commingled production. In order to study variation of reservoir performance model with time, tech of reservoir performance description is used to well test in multi-times in single well, analysis shows that formation model and reservoir factors don't vary in gas reservoir for long-term production. Formation model defined by reservoir performance description plays an important role on calculating productivity, predicting productivity and production in gas well etc. which has more practical significance than the statistic geology model.
