Abstract
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.
