A vertical profile of the 3D wellbore trajectory is generally.The challenge is how to draw the actual wellbore trajectory on the vertical profile of planned well trajectory.A planned 3D well path profile is depicted using vertical depth and projection length,however,the actual wellpath profile is supposed to be drawn using vertical depth and apparent projection length.

三维井眼一般都绘制垂直剖面图，其难点就是怎样在设计井眼轨道的垂直剖面图上描绘实钻井眼轨迹的剖面线，由于三维井眼设计剖面图是用垂深与投影长度绘制，其实钻井眼轨迹剖面图应该是用垂深和视投影长度绘制。
