摘　　要：低渗气藏开发中后期稳产难度增大,准确的预测气藏稳产期,及时调整开发方案是保证气藏充分开采的前提。该文结合产量不稳定分析法和物质平衡法,对井区内单井及井区整体稳产能力进行预测。研究结果表明该井区开发中后期单井稳产能力差距大,需要积极调整单井配产,以实现气田最大限度开采。It is difficult to keep the stable production,when low permeability reservoirs come into the mid-late period of exploitation.In order to improve ultimate gas recovery, adjusting development plan which depends on predicting stable productivity potential of the gas field is essential.This paper predicts stable productivity potential of single well and x well area both in RTA and material balance methods.The study shows that it is important to optimize the production-allocating to improve ultimate gas recovery in the mid-late period of exploitation.
