摘　　要：增压开采是气田开发中后期提高采收率的有效手段，需要对气井的生产动态进行准确的预测。针对目前靖边气田生产动态预测工作中存在的主要技术难题，利用物质平衡原理建立了定产条件下气井稳产时间的预测模型．预测了气井的增压时机，以产能方程为基础推导了气井定压降产阶段的产量预测模型，分析了产量递减规律．为靖边气田乃至长庆气田的持续、高效开发提供技术保障。In light of the Jingbian gas field production forecast dynamic in the work of the major technical problems, gas wells Stability time prediction model was established to determine the production conditions, using the material balance principle. The pressurized gas wells by the time predicted. Pressure Drop producing gas wells set the stage production forecast model was derived, based on the productivity equation. Analysis of the production decline, it has provided tech- nical support for the sustained and efficient development of Jingbian gasfield even Changqing Gasfield.
