摘　　要：为降低连续油管在注入过程中的损伤,延长其使用寿命,需要优化其在起下作业过程中的受力。针对连续油管注入头中的V形夹持块,取9组角度值,采用数值模拟的方法研究了夹持块取不同V形角度值时对应的连续油管的最大受力情况。通过试验台试验,验证模拟结果。利用BP神经网络将9组数据进行拟合,得出V形夹持块的最优夹持角度为60°。为连续油管作业机设计提供理论指导。Coiled tubing （CT）injector is the key component of the CT equipment,which is used to carry CT down into or out of the wellbore.To make the coiled tubing optimally pinched,thereby reducing the damage and prolong life,numerical simulation method was used to calculate the max-imum stress of the clamping block V-shaped angle with nine different sets of values.The numeri-cal results are validated by proceed experiment on an indoor platform.BP neural network was fi-nally used to see the best V-shaped angle,which would be 60＆#176;.The work of this paper would de-velop the theoretical basis for the manufacturing of CT injector.
