Application of Single Sided Directional Drilling Machine to Pipeline Construction in Large Loess Gully Region
Zhao Wen-ming, Zhou Xi-shu · Petroleum Engineering Construction · 2008
There are lots of large loess gullies distributed in partial regions where Luyang-Zhumadian product pipeline passes. The topography of the loess gullies is complex and steepy. In the construction of pipeline crossing these gullies, traditional artificial inclined well approach is often used and has some shortcomings such as low construction efficiency and safety. In Luoyang-Zhumadian product pipeline project, the inclined well was done by single sided directional drilling for the first time and achieved good effects of high construction efficiency and safety, easy and accurate slope control. In this paper the crossing construction method of inclined well done by single sided drilling is described and compared with the traditional method.
