斜孔钻探勘察作为一种勘察技术手段,却很少在油气管道非开挖穿越勘察领域中采用。定向钻和钻爆隧道是油气管道非开挖的主要穿越方式,如果能够通过斜向钻探查明穿越的地质条件,将有利于提高非开挖穿越的成功率,因此,研究斜孔钻探勘察在非开挖领域中的应用可行性非常有必要。调查研究结果表明:斜孔钻孔的设备和技术在油气管道非开挖穿越工程勘察中应用是可行的。通过实践发现,斜孔钻探在勘察过程中能够很好地配合常规钻探,有效地应对工程勘察中面临的一些地质勘察难点,通过斜孔钻探获取的勘察资料具有真实性、可信性、准确性及不可替代性,在很大程度上提升了油气管道工程的勘察水平,甚至在某些特殊的油气管道工程勘察项目中,能够发挥常规钻探不可替代的作用,因其独特的勘察视角越来越受到业界的广泛关注。
Slant hole drilling exploration as a means of investigation and technology, but rarely in the oil and gas pipelines in the field of non-excavation survey. Directional drilling and drilling and blasting tunnels are the main ways of non-excavation of oil and gas pipelines. If the geological conditions of crossing can be identified through oblique drilling, it will be helpful to improve the success rate of non-excavation crossing. Therefore, The feasibility of application in the field of trenchless is very necessary. The investigation and research results show that the equipment and technology of inclined hole drilling are feasible in non-excavation engineering exploration of oil and gas pipelines. Through practice, it is found that inclined hole drilling can cooperate well with conventional drilling during the investigation and effectively deal with some geological exploration difficulties encountered in engineering investigation. The survey data obtained through oblique hole drilling have the characteristics of authenticity, credibility and accuracy And irreplaceable, to a large extent, enhance the level of exploration of oil and gas pipeline engineering, and even in some special oil and gas pipeline engineering exploration project, can play an irreplaceable role of conventional drilling, because of its unique perspective of investigation more and more By the industry’s widespread concern.
