SYSTEM, APPARATUS, AND METHOD FOR DUAL-ACTIVITY DRILLING

摘要

Methods and apparatus for running a tubular into a wellbore. The method includes attaching a first member of a lifting coupling to a first tubular, and attaching a second member of the lifting coupling to a second tubular. The second tubular extends downward through an opening of a rotary station. The method also includes connecting together the first and second members of the lifting coupling, such that a weight of the second tubular is transmitted via the lifting coupling to the first tubular. The method further includes lowering the lifting coupling, the second tubular, and at least a portion of the first tubular through the opening, and disconnecting the second member from the first member. The method additionally includes moving the second member of the lifting coupling and the second tubular laterally, away from the opening.

1. A method for running a tubular into a wellbore, comprising:
attaching a first member of a lifting coupling to a first tubular; attaching a second member of the lifting coupling to a second tubular, wherein the second tubular extends downward through an opening of a rotary station; connecting together the first and second members of the lifting coupling, such that a weight of the second tubular is transmitted via the lifting coupling to the first tubular; lowering the lifting coupling, the second tubular, and at least a portion of the first tubular through the opening; disconnecting the second member from the first member, after lowering the lifting coupling, the second tubular, and the at least a portion of the first tubular; and moving the second member of the lifting coupling and the second tubular laterally, away from the opening.
