摘要： 从 Arps 的基本递减规律出发,提出了一种低渗透气藏递减规律的简单分析方法。指出了低渗透致密气藏气井递减率并非恒定不变,对衰减递减方程进行变形并推导出产量预测模型,对模型中的系数进行修正,使其能很好地拟合实际生产数据。此方法以月为单位使计算更加准确、合理。通过油田实际应用表明,该方法简单、可靠、实用,对于产量波动较大的低渗透和特低渗透气藏尤为适用。

关键词: 低渗透油气藏, 产量递减, 拟合, 预测

Abstract: Based on the basic decline rule of Arps, this paper presents a simple analysis method for decline regularity of low permeability gas reservoir. It points out that the production decline rate of gas well in such a compacted gas reservoir is not constant. The deformation of the attenuation decline equation is made, and a production prediction model is deduced with modified coefficient for better matching the production performance in terms of month rather than year in unit. The field application indicates that this method is simple, reliable and practicable for prediction of low, especially supper-low permeability gas reservoir with greater yield fluctuation.

Key words: low permeability reservoir, production decline, history match, prediction, forecast
