油气井杆管柱力学在微米/纳米系统中的应用前景

油气井作业中的杆管柱在充满流体的狭长井筒内工作,在各种力的作用下,处于十分复杂的变形和运动状态;油气井杆管柱力学已经初步形成系统,并在石油工程上得到了越来越广泛的应用。随着碳纳米管材料和微机械在现代应用科学领域的异军突起,在该领域中也遇到了类似的杆管柱强度和作业问题。本文基于对油气井杆管柱力学的认识和理解,从跨学科应用的角度出发,探索油气井杆管柱力学在微机械和碳纳米管领域的应用前景。

Application Possibilities of Tubular Mechanics in Oil-gas Wells in Micro / Nano Systems

While working in a long and narrow fluid-filled wellbore during drilling and production,affected by a variety of forces,the rod and pipe string will fall into a very complex state of deformation and movement.Tubular mechanics in oil-gas wells is now established systemically,and has broad applications in petroleum engineering.With the violent development of the carbon nanotube materials and micro-machinery in the modern science,similar tube strength and operations will be encountered.In this paper,based on the awareness and understanding of tubular mechanics in oil-gas wells,from an interdisciplinary point of view,possibilities of applying tubular mechanics in oil-gas wells into micro-mechanical and carbon nanotube fields have been discussed.
