定向钻双曲线技术在施工中的应用
Application of Directional Drilling Hyperbolic Technology to Construction
摘要
Abstract
As the city pipeline network encounters more obstacles during construction phase, pipeline laying is inadequate of space. To resolve the above problem, in which case of Oujiang Road crossing project of CNOOC Lishui 36 -1 Gas Field Land Pipeline was illustrated, horizontal azimuth angle was repeatedly constructed in confined space by using hyperbola construction technique ( superimposed curve) of horizontal directional drilling. This paper proposes the solutions and provides new idea of pipeline laying under limited site condition.关键词
