Abstract:

Tubular strings are considered as the backbone and central nervous system for oil drilling and production operations in oil and gas wells. Tubular mechanics in oil and gas wells is the most important basic and applied science in petroleum and natural gas engineering. In this study, the monographs on tubular mechanics, the scholars engaged in this field and relevant research methods were introduced and some basic concepts were clarified firstly. Then, this study focuses on the research advances and debates on the fundamental principles and basic equations of tubular mechanics, the motion states, stability and steady state tension-torque of tubular strings, the 3D mechanical analysis of bottom hole assembly, the dynamic analyses of drill strings, the mechanical analyses, casing strings, testing strings and fracturing water injection/steam injection tubular strings, the diagnosis, parameter optimization and energy saving of rod pumping system, the vibration of gas production tubular strings, the impact vibration of strings, the mechanical analyses of swelling screen pipe/casing and riser strings, the propagation of vibration wave signals in strings, as well as string wear, corrosion and erosion, and the residual strength and fatigue strength forecast of strings. Finally, the key directions for future research are prospected.

Key words: drill string, casing, tubing, pumping rod, riser, mechanics, vibration, advance, debate
