    Abstract: A member is moved within a well bore in a plurality of cycles, each cycle comprising holding the member in slips, releasing the slips, moving the member within the well bore and applying the slips. The hook load is measured at multiple points during each of these cycles and the plurality of measured values are used to identify data indicative of the forces on the member within the well bore.

    Abstract translation: 一个构件在多个循环中在井眼内移动,每个循环包括将构件保持在滑移中,释放滑移件,使构件在井眼内移动并施加滑移。 在这些循环中的每个循环期间,在多个点处测量挂钩负载,并且使用多个测量值来识别指示井眼内的构件上的力的数据。
