摘要： 由于水平井具有高渗流面积和低渗流阻力的特点，其产量较高，近15年来，水平井开采技术在中国油气田的开发中得到了广泛的应用。最常见的用于水平井产能评价的水平井产量公式有 Borisov 公式、Joshi 公式、Giger-Resis-Jourdan公式、Renader-Dupuy公式和陈元千公式等。基于5种常用水平井产量公式的对比研究，提出了水平井产能指数、渗流阻力、表皮因子、非均质性和偏心距等指标的评价方法。

Abstract: With the feature of high seepage area and low flow resistance, horizontal?well technology has been widely applied to the development of oil and gas fields in our country due to its high productivity. Meanwhile, various kinds of production rate formulas are often used to evaluate the productivity of horizontal wells. The main production rate formulas for horizontal wells which have been valued and applied in our country include: Borisov formula, Joshi formula, Giger?Resis?Jourdan formula, Renader?Dupuy formula and Chen Yuanqian formula. At present, these formulas are not used effectively because the difference and uncertainty of these formulas have not been enough mastered. In this paper, some comparisons of these formulas were studied, and some evaluation methods were also proposed, including productivity index, equivalent flow resistance, skin factor, heterogeneity and eccentricity, etc
