斜井钻孔路径任何钻孔drilled in a direction that deviates from the standard vertical planar direction. This term is commonly used to describe the type of bore path created in directional drilling techniques. Non-vertical bore paths may be at any angle other the vertical gravity direction and may also possess a radius of curvature.
Trenchlesspedia Explains Non-Vertical Bore Path
One of the main characteristics distinguishing non-vertical bore paths from tradition vertical bores is the type of equipment used to create the bore. Non-vertical bore paths are usually created by directional drilling methods using steerable drill heads. The drill bit is launched at an entry site where a walkover locator is used to monitor the direction of the drill bit. The information from the locator is transmitted to a control cabin where an operator uses a set of controls to adjust the angle and direction of the head.
Non-vertical bore paths are typically used to facilitate the installation of underground pipes, conduits, and cables under overhead obstructions.
