视轨道

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。

At a recent show he unveiled four new pets: a portable lightning machine that spits 9-foot bolts of crackling blue lightning at nearby machines; a 120-decibel whistle driven by a jet engine; a military rail gun that uses magnetic propulsion to fire a burning comet of molten iron at 200 miles per hour, which upon impact explodes into a fine drizzle of burning droplets; and an advanced tele-presence cannon, a human/machine symbiont that lets a goggled operator aim the gun by turning his head to gaze at the target. It fires beer cans stuffed with concrete and dynamite detonators.

最近的一次秀场上他推出了4只新宠物：一台便携式闪电机，对着近旁的机器武士喷吐出9英尺长劈啪作响的蓝色闪电；一只由喷气机引擎发动的120分贝汽笛；一门军用的电磁轨道炮，发射时速200英里的热熔铁疙瘩，彗星样的火球在空中爆裂开来，变成燃烧的毛毛细雨洒落下来；还有一门先进的远地视在[3]人机一体加农炮，戴着虚拟视镜的操控者转动自己的脑袋盯住目标就可调整炮口的瞄准方向，而炮弹是塞满雷管炸药和混凝土的啤酒罐。
