摘要
连续油管注入头是连续管作业设备中操控连续油管下入和上提的重要装置,连续油管和摩擦块配合直接影响连续油管的工作性能与寿命,也决定着两者之间的夹持可靠性,直接影响到连续油管作业设备的安全。从连续油管作业设备中摩擦块与连续油管之间的接触工况入手,以11/2英寸连续油管设备注入头为对象,研究管-块接触时的受力状态,借助有限元分析软件,建立有限元分析模型并进行模型的参数化设计,通过对不同组合的管-块配合模型进行分析,求得连续油管-摩擦块之间的最优配合。
The CT injector head is an important part of CT unit by which CT is been deployed into or pulled out of the well.The tolerance between CT and friction block affects the working performance and durability of injector head,decide the grip reliability between CT and friction block and affects the security of CT unit directly.Starting with touch behavior between friction block and CT,based on 1 1/2 inch CT unit injector head,the thesis studies the touch stress state,found the finite element analysis model,and proceeds design of parameterising model.And then the optimum tolerance between CT and friction block is gained through analysis of finite element of various combination.
