摘要
利用测斜资料，采用全角曲率理论来计算钻孔弯曲曲率、曲率半径及大直径井管的弯曲应力，以指导在深孔中安全地下入大直径井管，避免井管折断事故。
By using of inclination measurements and on basis of the full angle curvature theory, the drill well bent curvature, curlature radius and stress of large diameteer well casing are calculated to guide safely placing large diameter well casing in deep wells and avoiding well casing bucling failure.
