| 摘 要： | 定向井的载荷计算是一个相当复杂的问题.目前所采用的方法是取井筒中一小单元进行受力分析,然后逐段叠加.这一过程需要输入井斜数据后利用计算机辅助进行,在现场应用中很不方便,且由于受各种因素的影响,其计算结果仍然是一个近似值.通过对现场多口井实测载荷的分析比较认为,传统的直井载荷计算公式经过一定的经验系数修正后仍然可以应用于定向井载荷的近似计算.

| Abstract: | Load calculation of the directional well is a very complex problem,the method used is a small unit to take wellbore stress analysis,and then paragraph by paragraph superposition.The use of computer aided this process need to enter the well deviation data,and inconvenient in the field application,and due to the influence of various factors,the calculation is still an approximation.Through the analysis of on-site wells measured load that traditional vertical wells load formula after some experience factor correction can still be applied to the approximate calculation of the directional well loads. |
