摘要: 介绍了水平井稳态产量公式的推导思路与推导过程,根据水平井的渗流场特征,对常用的水平井产量公式(Borisov公式、Giger公式、Joshi公式、Renard-Dupuy公式)进行了对比分析。通过分析发现,水平井产量公式在推导过程中存在疏漏,应予以修正。通过实例计算,证明了修正后的水平井产量公式与Borisov公式、Giger公式、Renard-Dupuy公式等在计算结果上有很好的一致性,实现了水平井产量公式在形式上的统一。

Abstract: This paper introduces the deducing ideas and processes of steady?state productivity formulas for horizontal wells, and compares the commonly used formulas. Through the analysis, it is indicated that there are loopholes in the process of deducing the productivity formulas for horizontal wells, which should be corrected. There are little differences among the modified formula, Borisov’s formula, and RenardDupuy’s formula in the calculation results, thus providng the validity and practicability of the modified formula, and realizing the unification of productivity formulas for horizontal wells in form
