【摘要】 对水平井的产能公式进行了细致的研究，尤其对Joshi的产能公式进行了重点分析。根据Giger和Joshi的假设，用保角变换方法重新推导了水平井的产量公式，发现Joshi公式中分母第二项少了一个“π”。进一步用等值潜流阻力法推导出在椭圆边界和直线供油边界条件下水平井产能公式。结果表明，用等值渗流阻力法很容易解决水平井的干扰问题和水平井开发方案的概念设计问题。更多还原

【Abstract】 This paper analysis in detail Joshi’s productivity equation of a horizontal well. On the basis of Giger and Joshi’s assumptions,the productivity formulae of a horizontal well is anew derived with con form transformation, and compared with Joshi’sequation. The results demonstrates that a "ff" in Joshi’s formula is omitted, which is an obvious default. The horizontalproductivity formulae in the reservoir with el1iptic boundary and linear boundary at constant pressure is developed by use ofequivalent flow resistance’ Based on these studies, the equivalent flow resistance method can be conveniently applied to solveinterference probIems of the horizontal wells and is very useful for the conceptual design of development plan with horizontalwells.更多还原
