摘　　要：针对分层开采井生产特点,建立考虑层间干扰的分层优化配产模型。该模型的特点为:将天然气从地层到井底的流动看作多压力系统(相当于多井生产),从井底到井口的流动认为是单压力系统(相当于单井生产),通过优化井下气嘴和考虑合理产量影响因素配产使各分采层段的产能达到最大。对该模型求解并编制软件,利用该软件可确定分层开采气井的合理产量,优化相关工艺参数,从而使分层开采时各层达到最优的产能贡献。An optimization model of separate production allocation is established with consideration of interlayer interference in accordance with the production characteristics of separate zone production wells.This model regards gas flow from reservoir to bottom hole as a multi-pressure system(equivalent to multi-well production) and from bottom hole to wellhead as a single pressure system(equivalent to single well production).It optimizes downhole gas nipple and allocates production amid different layers by taking account of influencing factors to achieve maximum production.The model is solved and its software is developed.This software can determine the reasonable production of a gas well producing from separate zones and optimize relative technical parameters,thus realizing optimal production contribution from each layer.
