悬重 WOHxcs 悬重即是大钩负荷(hook load),在起下钻中,大钩负荷可能不等于井内钻具重量,它是判断起下钻遇阻的重要依据。泵冲 PUMP1、2、3 泵冲数是分泵检测的。

Pick up drill string to setting depth, record hook load of the drill string;
上提钻柱至坐封深度,并记录钻柱悬重;
Tense the raising lines with hook load about 150 kN, and check key parts for any abnormality.
提紧起升绳至钩载150kN左右,观察各关键部位有无异常。
Compared the calculated data with the field data, the errors of the hook load was less than 5% and that of torque was less than 7%.
通过与现场试验数据相比较,对钩载的预测误差小于5%,对扭矩的预测误差小于7%。
