Filed:

Dec 2, 2008

Appl. No.:

12/745676

Inventors:

Ronald G. Earles - Houston TX, US
Barry D. Calnan - Conroe TX, US
Randy C. Ivey - Spring TX, US

International Classification:

E21B 7/08
E21B 10/60
E21B 17/10
B23P 17/00

US Classification:

175 76, 175393, 1753252, 2989009

Abstract:

Sleeves, stabilizers and other well tools may be formed with fluid flow paths or channels extending through one or more blades disposed on the exterior portions of such well tools. The blades and associated fluid flow paths extending therethrough may allow optimum fluid flow rates and volumes to enhance lifting of formation cuttings and downhole debris along with cleaning exterior portions of the well tool and an associated rotary drill bit. Location, configuration, orientation and/or dimensions associated with such blades and associated fluid flow paths or channels may also be modified to provide an enlarged pad or contact surface on exterior portions of one or more blades while maintaining desired fluid flow rates and volumes over exterior portions of the well tool. Such pads or contact surfaces may have optimum surface areas for contacting adjacent portions of a wellbore during directional drilling of the wellbore.

Abstract:

A well tool can include multiple sections, one section having a mating weld surface formed thereon, and another section having another mating weld surface formed thereon. Engagement between the mating weld surfaces can prevent lateral displacement of the well tool sections relative to each other. The mating weld surfaces are welded to each other. A method of constructing a well tool can include engaging a mating weld surface on a section of the well tool with another mating weld surface on another section of the well tool, an interface between the mating weld surfaces being inclined relative to a longitudinal axis of the well tool extending through the sections, and welding the mating weld surfaces to each other along the interface.
