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, said system comprising:
a drilling deck having a well center; a primary tubular advancing station configured for advancing a first tubular onto said drilling deck from a substantially horizontal position to a substantially vertical position above said well center; a stand arm disposed with said drilling deck and configured for handling a second tubular; and a guided path horizontal to vertical arm positioned adjacent to said stand arm and configured to guide the second tubular onto said drilling deck from a substantially horizontal position to a substantially vertical position adjacent to said stand arm, wherein said guided path arm is configured to guide the second tubular onto said drilling deck during advancing of the first tubular onto said drilling deck to said well center and said guided path arm is configured to operate independently of said primary tubular advancing station.
