四点法和三角形井网水平井产能公式研究

PRODUCTIVITY FORMULA OF HORIZONTAL WELLS IN FOUR SPOT AND TRIANGULAR PATTERNS

用保角变换法和等值渗流阻力法推导出了气顶底水油藏四点法井网水平井产能公式及封闭边界油藏三角形井网水平井产能公式，考虑了水平井之间井距、排距、水平井位置、油藏各向异性比值等因素对水平井产能的影响。最后进行了实例计算。

By applying conformal transformation and eguivalent seepage resistance method,this paper derives productivity formula of horizontal wells beth in four spot pattern in reservoir with gas cap and bottom water,and in triangular pattern in reservoir with closed boundaries during the process of which the factors affecting the productivity of horizontal wells,such as the distance between wells and rows,location of horizontal wells and reservoir anistropy ratio etc.are considered.At last,case calculations are performed.
