分支井单位长度产能随着分支与主井眼夹角角度、分支长度的增加而增加，随着分支数量的增加而逐渐降低。
Gas production per unit length increases with the increase of branchlength and the angle between main and branch boreholes. However, it declines as the number of branches increase.
边角度：如果开启，将以角度在两个选择边的夹角显示该角的角度，边必须被连接形成一个角。
Edge Angles - If this is selected the Angle in degrees will be drawn near the corner of two selected edges. The edges must be connected to the same corner.
