发明名称 MAKE-UP CONTROL SYSTEM FOR TUBULARS
摘要 <p>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 least 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 are applied to the first tubular (106) during a make-up process between the first and second tubulars. The top drive (101) also generates a torque feedback signal that is transmitted to the controller (102) so that the controller can 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 make-up process when a predetermined torque limit is reached.</p>
