摘要: 利用镜像反映及势函数的叠加原理,导出了气顶油藏中任意一点的势函数,推出了气顶油藏中水平井井底势差和水平井的产量方程,研究了水平井的位置对气顶油藏水平井产量、临界产量及气锥时呵的影响,获得了气顶油藏中水平井的合理位置。

关键词: 水平井, 气顶油藏, 势函数, 气锥时间, 合理位置

Abstract: Utilize mirror image reflect and potential function's princi-ple of superposition,priority elicit any point's potential function in gas-cap reservoir,then fetch the bottom potential difference and output equation of horizontal well in gas-cap reservoir,therefore we studied the influence of the horizontal well position to production rate of a horizontal well critical rate and gas migra-lion time in gas-cap reservoir, so obtain the horizontal well's reasonable position in gas-cap reservoir.

Key words: horizontal well, gas-cap oil reservoir, poten-tial function, gas coning time, reasonable position
