摘要
为了研究井孔偏斜弯曲对井管的不利影响 ,首先对井管弯折产生的原因、过程、方式进行分析 ,然后应用材料力学知识 ,推导出附加弯矩及挤压力的理论计算公式 ,可以方便地在井管横断面设计。
In order to research the disadvantage influence of well-hole deflection bend to well tube, first, the cause, process, and the ways of bend and break of well tube are analyzed; then, the theoretical calculation formula for appending bend moment and extrusion pressure are deduced by using material mechanics, and the formula can be used conveniently in the cross-section design, connection design and verification calculation of well tube.
