摘    要:水平井是提高油气井产能的重要手段,它除了具有超长的生产井段和较大的渗流面积之外,还具有显著的井底有效半径和较大的负表皮系数.因此,水平井具有较高的产量和产能比.根据水平井产量的新公式,提出了确定水平井井底有效半径、表皮系数和产能比的新方法,并与Joshi方法进行了有效对比,取得了一致的结果.

关 键 词:水平井  井底有效半径  表皮系数  产能比  水平井  有效井底半径  负表皮系数  产能比  结果  有效对比  方法  公式  井产量  有效半径  面积  渗流  井段  生产  手段  油气井产能

Abstract:Horizontal well is an important method to increase the production of oil and gas. Except for its super-long producing interval and relatively big filtration area, it also has obvious effective bottom hole radios and relatively big minus skin factor. So horizontal well has relatively high production and productivity ratio. The paper uses the new formula of horizontal well production to give a new method to determine the effective bottom hole radios horizontal well, skin factor and productivity ratio. Meanwhi...
Keywords:horizontal well  effective bottom hole radios  skin factor  productivity ratio
