Simultaneous tubular handling system

摘要

A system and method for building and handling oilfield tubular stands while drilling operations are simultaneously and independently occurring with one drilling deck, one derrick, and one rotary system. An offline guided path horizontal to vertical arm lifts and moves in the same plane tubulars stored horizontally on the catwalk and positions the tubulars vertically directly into a preparation hole for assembling and disassembling tubular stands while online drilling operations are simultaneously being conducted. A stand arm lifts and lowers the tubulars into and out of the adjustable preparation hole, and transports the tubulars for storage to an auxiliary tubular racking station in the upper part of the derrick. A bridge racker crane moves tubular stands from the auxiliary tubular racking station to the top drive or another tubular racking station.

主权项

1. A system for drilling, comprising:
a drilling deck having a well center; a first tubular; a second tubular; a drilling structure disposed with said drilling deck; a primary tubular advancing station configured for advancing the first tubular to said well center; a stand arm disposed with said drilling structure and configured for positioning the second tubular in a substantially vertical position, wherein said stand arm is configured to operate during advancing the first tubular to said well center and independently of said primary tubular advancing station; a first tubular racking station above said drilling deck and adjacent to said stand arm configured for holding the second tubular; and a bridge racker crane configured for moving the second tubular between said first tubular racking station and said well center, wherein said stand arm is configured to directly position the second tubular with said first tubular racking station.
