Filed:

Dec 1, 2016

Appl. No.:

15/366922

Inventors:

David B. Wagner - Houston TX, US
Brent Lane - Houston TX, US

Assignee:

Inrock Drilling Systems, Inc. - Houston TX

International Classification:

E21B 10/28
E21B 10/60
E21B 7/28
E21B 7/04

Abstract:

Embodiments of a reamer of the present invention generally include a substantially tubular body sub, a substantially planar base plate having one or more receiving cavities disposed therein, one or more gussets, a fluid chamber, and a plurality of leg/cone assemblies having a leg end and a cone end; wherein the base plate is disposed around the body sub and stabilized by the gussets, and each leg end comprises an exterior surface geometry complementary to the interior surface geometry of a base plate receiving cavity and is insertable into and affixable therein. The receiving cavities are constructed in defined locations and orientations in the base plate and the leg/cone assemblies are precisely formed such that insertion of the leg end into the receiving cavity accurately and precisely disposes the cutting component about the reamer. Embodiments of methods of providing and using an apparatus of the present invention are also provided.

Abstract:

A borehole reaming cutter retention and fastening/locking system enable field replacement of borehole reaming cutter assemblies utilized in infrastructure emplacement horizontal drilling (HDD) applications. The borehole reaming cutter assembly retention/fastening system can withstand borehole drilling forces without the necessity of permanent welding, thereby allowing cutter interchangeability/replacement in the field. The borehole cutter retention assembly shape and design, coupled with the fastening/locking mechanism design, may be robust enough to replace permanent welding and may allow field cutter interchangeability and replacement. Current designs and devices utilize permanent welding of component/cutter assemblies, thereby requiring workshop/welding construction and deconstruction to enable the interchangeability and replacement of cutter assemblies.
