The present disclosure provides a method for running a drilling rig or a workover rig including a plurality of stands into a wellbore. In step 1, position information of the stands in a finger board area may be recorded with a control system. In step 2, the stands may be placed. In step 3, a position of a traveling block may be adjusted so as to move a power elevator to a second waiting position of a racking platform. In step 4, the stands may be pushed with the pipe racking device. In step 5, the second stand may be moved and stabbed in the first stand with an iron floor man. In step 6, a joint between the first stand and the second stand may be made up. In step 7, the traveling block may be moved downward. In step 8, the traveling block may be moved upward.

Methods for tripping a drilling rig or a workover rig

A pipe racking system includes a diving board having a guide rail, a trolley, a manipulator, and a gripper. The trolley has two sides being mounted to the diving board via the guide rail and being driven by a rack and pinion member. The gripper is connected to an end of the manipulator away from the trolley. The trolley includes two pairs of combined bearings and two pairs of eccentric wheels. The gripper is configured to grip a tubular subject and include two opposing flippers, two first electric putters, and two springs. The two first electric putters is configured to control the two flippers. One end of each spring of the two springs is connected to a flipper of the two flippers and the other end of the each spring is connected to a push rod of a first electric putter of the two first electric putters.
