    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: 一个构件在井眼内以多个循环移动,每个循环包括将该构件保持在滑动中,释放滑动,在井筒内移动构件并施加滑动。 在这些循环中的每个循环期间在多个点处测量吊钩载荷,并且使用多个测量值来识别指示井筒内部件上的力的数据。
