摘要: 随着越来越多的水平井应用于天然气藏,确定准确预测水平气井产能公式意义重大。基于国内外学者由油藏推导的水平井产能公式不能直接应用于气藏,在详细介绍了水平井产能公式研究进展的基础上,利用陈志海等提出的方法对不同学者的油藏水平井产能公式进行改进,得到了气藏水平井产能公式。通过实例计算对比发现,被广泛用来计算油藏水平井的Giger、Joshi公式在计算气藏水平井产能时精度太低,而Borisov、Renard和Dupuy、郎兆新、陈元千公式计算结果与实际产量的相对误差在10%以内,更符合现场应用的需要。对以后的气藏水平井产能研究有一定的借鉴意义。

Abstract: As more and more horizontal wells are drilled in gas reservoirs,determination of accurate deliverability formulas is of great significance.Because deliverability formulas of horizontal oil wells cannot be directly used for horizontal gas wells,after introducing research progress of horizontal well′s deliverability formulas,deliverability formulas of horizontal gas wells are obtained from improving the deliverability formulas of horizontal oil wells by using the method proposed by CHEN Zhi-hai etc.Through comparing the results of these formulas,Borisov,Renard,Dupuy,LANG Zhao-xin and CHEN Yuan-qian formulas are of higher precision than Giger,Joshi formulas which are widely used in horizontal oil wells.It is of reference for future deliverability study of horizontal gas wells.

Key words: horizontal gas well, deliverability, formula, progress, application
