摘要
介入医学是依靠医学影像设备的引导,利用穿刺和导管技术对疾病进行诊断和治疗并以治疗为主的一门学科,是一门独立于内、外科的新兴医学学科,国家正式命名为第三大诊疗技术。介入治疗包括血管性介入治疗和非血管性介入治疗。血管性介入治疗的关键部分是导管和导丝在血管中的作业。通过比较发现,导管和导丝在血管中的作业过程与油气井杆管柱在井筒中的作业过程十分相似。油气井杆管柱力学是在石油工程领域较系统、成熟的力学理论体系。本文主要引述了其中的拉力—扭矩模型,并应用定向井钻柱力学分析软件对模拟血管中导管作业进行了力学分析。
Medical intervention is to make use of puncture and catheterization technique for the diagnosis and treatment,relying on the guidance of medical imaging equipment.It is also a new medical branch which is independent of internal medicine and surgery.It is officially named the third largest medical technology.Interventional therapy contains blood vessel intervention and non-vessel intervention.The operation of the catheter and thread in the vessel is the key part of vessel intervention.By comparison it is found that the operation of catheter and thread in the blood vessel is similar to that of the string in the wellbore.Tubular mechanics in oil-gas wells is a mature theoretical mechanics system in the field of Petroleum Engineering.In this paper,the tension-torque model of the tubular mechanics in oil-gas wells is introduced,and the operation of catheter in a simulative vessel is mechanically analyzed with the software of mechanical analysis of drill string in directional wells.
