Benefits of technology
"The present invention provides a method and apparatus for forming a stand from tubulars. The method involves loading two tubulars on a stand forming apparatus, rotating them about their longitudinal axes in opposite directions, and advancing one tubular against the other to engage cooperating threads on each end to form a stand. The apparatus includes a catwalk and a pulling means for gripping and pulling the tubulars towards the rear end of the catwalk, a pushing means for advancing the tubulars to the front end of the frame, and a rotating means for rotating the tubulars. The technical effects of this invention include improved efficiency and accuracy in the formation of stands from tubulars."
Problems solved by technology
The addition of a tubular to an existing drill string is a relatively time consuming and dangerous procedure.
As such, the frequency of adding tubulars to the drill string is high and, therefore, the efficiency of the drilling operation is hampered.
In addition, the above described manipulation of the tubulars often requires manual handling and, therefore, increases the risks to the drill rig personnel.

Embodiment Construction
[0031] As described further below in more detail, the present invention provides an improved apparatus for forming stands from individual tubulars. In general, the invention comprises a catwalk onto which are loaded two tubulars. The tubulars are positioned generally coaxially on the catwalk in an end-abutting arrangement. The catwalk is provided with lifting devices comprising, in one aspect, actuating arms having rollers that contact and raise the tubulars above the level of the catwalk. The rollers are driven by one or more motors and are arranged so that the tubulars are axially spun in opposite directions with respect to each other. During the spinning operation, the tubulars are advanced against each other whereby the complementary threads on each end engage to form a connection, thereby forming a dual tubular stand. As will be understood, the tubulars are arranged so that the male and female ends are in abutting arrangement so as to permit engagement. The arms are then lowere...

A catwalk apparatus for forming stands from individual tubulars comprises a frame having a top surface adapted to receive tubulars. The apparatus also includes a skate mechanism capable of pushing and pulling the tubulars once loaded on the apparatus. The apparatus is adapted to receive at least two tubulars in a coaxial arrangement. The apparatus includes a rotating means for oppositely rotating the tubulars along their longitudinal axes. The skate mechanism is used to advance the tubulars together during rotation so as to allow cooperatively threaded ends of the tubulars to engage thereby forming a stand. The skate mechanism is also used to urge the stand towards the drill rig for subsequent hoisting and orienting vertically. A method and system for forming tubulars is also provided.
Description
CROSS REFERENCE TO PRIOR APPLICATIONS [0001] This application claims priority from Canadian application number 2,540,820, filed on Mar. 21, 2006, the entire contents of which are incorporated herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to pipe handling apparatuses and, more specifically, to apparatuses and methods for drilling operations wherein stands are formed from tubulars. DESCRIPTION OF THE PRIOR ART [0003] Various ground drilling operations are known such as exploring and / or extracting oil from subterranean deposits. The drilling operation is conducted on a drill rig comprising a raised drilling platform located above the drilling location. A denick is provided on the platform to raise, support and rotate a drill string. A drill string includes a drill bit for boring into the ground. As the drilling operation continues, tubular members, commonly referred to as “tubulars” are connected in an end to end manner to form a drill string. Tubular...
