摘　　要：油管的最大下入深度与油管本身的强度、密度、油管内外压差、井中流体对油管柱浮力有关。通过对组合管柱的受力分析,依据推导的公式,找到了一种采用图板进行油管柱最大下入深度和强度校核的方法。The maxim setting depth of tubing is related to its strength, density, inner and outer pressure difference as well as wellbore fluid＇s buoyant force to tubing string. This paper deduced equation by analyzing strength endured by tubing string, based on formula, taking advantage of graphical method checkout the maxim setting depth and strength.
