准噶尔盆地西北缘K82井区佳木河组气藏毗邻城市在冬季供气中作用重要,现今仍具丰富的剩余储量,但井间生产差异大、产能主控因素不明制约着气藏稳产和新井部署。本文综合气藏生产动态与地质特点,总结气藏生产特征并分析影响生产的主要因素。结果表明:气藏具有初期高压高产但递减快、低压低产较稳定但携液困难的生产特征,构造条件对生产影响不大,储层条件是影响生产的主要因素,积液突然排出引起产气量波动对稳产不利。
In the northwestern margin of the Junggar Basin, the Karyuhe Formation gas reservoir in the adjacent K82 zone plays an important role in winter gas supply, and today it is still rich in residual reserves. However, there are large differences in production between wells, with unclear factors of production capacity restricting stable gas production and new wells deploy. In this paper, gas production dynamics and geological characteristics of integrated gas production characteristics and analysis of the main factors affecting production. The results show that the gas reservoirs have the features of high initial productivity and high yield but rapid decrease, low pressure and low yield but stable production but difficult liquid-carrying characteristics. The structural conditions have little effect on the production and the reservoir conditions are the main factors affecting the production. The sudden discharge of effusion causes gas production Volatility is bad for steady production.
