MAKE-UP CONTROL SYSTEM FOR TUBULARS

摘要

A make-up control method and system (100) for creating a threaded connection between a first tubular (106) and a second tubular (114) is provided. The system (100) includes a top drive (101) connected to the first tubular (106) and a controller (102) operably connected to the top drive that sends at lea st one command signal to the top drive. The top drive (101) generates a torque and a rotational speed in response to the at least one command signal that a re applied to the first tubular (106) during a make-up process between the firs t and second tubulars. The top drive (101) also generates a torque feedback signal that is transmitted to the controller (102) so that the controller ca n monitor the torque and the rotational speed that are applied to the first tubular (106) during the make-up process. The controller (102) halts the mak e- up process when a predetermined torque limit is reached.
