摘    要:在充分考虑气举的卸载过程特征的基础上,采用质量守恒和动量守恒方程及地层中的非稳态渗流方程,建立仿真模型;采用有限差分方法求解,给出详细的计算步骤,并编制了计算机软件.仿真实例表明,用本所述方法,可以描述气举井系统在卸载过程中的压力、液面、注气量、产液量等随时间变化的动态,为气举井的合理设计和分析提供了有力的工具.

关 键 词:采油工程  气举井  卸载过程  动态仿真  有限差分方法  数学模型  压力  液面  注气量  产液量

Abstract:Considering the characteristics of unloading process, the simulation model of the gas-lift unloading is established with the equation of conservation of mass, the equation of conservation of momentum, and transient seeping equation. The finite difference numerical solution scheme of the model is given and the computer programming is developed. The simulation sample shows that the simulating method presented can describe the changes with time of pressure,liquid level, injecting gas, liquid production rate etc. It provides a powerful tool for reasonable design and analysis of gas-lift wells.
Keywords:petroleum production  gas lift  gas lift unloading  simulation
