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 ,然后逐段迭加。这一过程需要输入测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后认为 。It is a complex problem to compute hanger position burden of pumping unit in directional well. At present,the common method is to select a small unit,then analyses its force.But this process needs the well testing data and the aid of computer.It is inconvenient to apply on the spot,and the calculation result is an approximate value.Through comparison and analysis of large number of measured burden data for many wells,the results show that the traditional load calculation formula for vertical well can be used in approximate calculation of directional well load after modifying several practical factors,and it facilitates the field application.
