水驱气藏单井动态优化配产方法研究

针对国内外气井（藏）配产和设计中存在的工程问题，引入生产时间的概念，建立了水驱气井（藏）的动态优化配产模型。该模型改变了传统意义上用绝对无阻流量配产计算过程，对生产数据的依赖性小，可以减少因人为因素造成的配产不当和设计失误。特别是具有天然水侵的气藏，如果产量配置不合理，造成井底积液，严重影响气井产量，因此时水驱气藏动态优化配产具有更重要意义。

Method of Dynamic Optimization of Production Allocation of Single Well in Water Flooding Gas Reservoir

Aiming at engineering problems existing in production allocation of gas wells both at home and a-broad, this paper introduces time concept to construct dynamic optimization model of production allocation of water flooding gas well ( reservoir). This model changes traditional calculation process with absolute open-flow capacity, and is less depending on production data. It can reduce unreasonable allocation of production and design caused by man-made factors, especially for gas reservoirs with natural water influx. Unreasonable production allocation may cause bottom hole fluid accumulation and reduce gas well production. Thus dynamic optimization of production allocation of water flooding gas reservoir is important.
