摘要: 以单井开采系统为研究对象,采用温度、压力解耦建模与数值耦合方式,以井口油压为控制条件,通过油嘴控制流量和下游温度,建立井下节流气井的井筒-气藏流动耦合的生产动态预测模型,利用试井解释结果或生产动态历史拟合,预测气井的生产流量、压力变化,同时描述生产过程中的井筒非线性温度剖面、压力剖面,从而全面掌握节流气井的生产动态,并可进一步扩展应用于多相流动和复杂井眼轨迹情况。

关键词: 井下节流, 耦合模型, 动态预测, 温度场

Abstract: The production prediction model of down-hole throttle gas well with well-bore and gas reservoir flow coupling is established in this paper,the temperature and pressure decoupling model and numerical coupling is adopted for single-well production system.It takes tubing-head pressure as setting conditions,rate and downstream temperature are controlled by choke,which can forecast rate and pressure change of gas well by well-test interpretation and history match,and nonlinear well-bore temperature and pressure profile in production process are described.Accordingly,the production performance of throttle gas well can be investigated comprehensively.The route can be extended to multiphase flow and complex well trajectory.

Key words: downhole throttle, coupling model, performance prediction, temperature field
