Simulator and calculating model for friction force on the the well completion string in the large displacement well

根据现场完井工艺和研究完井管柱受力情况 ,文中导出了一种简易实用的完井管柱上提、下放的载荷计算模型。进一步提出开发仿真器的基本思路和介绍具体的数值计算处理办法。实例计算表明 ,理论计算结果与现场实测结果基本相符 ,从而验证了计算模型的准确性。无疑 。

On the bases of force analysis on the well completion string and technoloy of well completion,the calculating model for forces on the string is deduced.And the developing idea about simulator and calculating method are put forward.The example shows that the model is correct,because theoritical result is identical with pratical.Undoubtedly,the study has pratical value in predicting the friction forecs on the well completion string.
