Abstract

A filter system for filtering drill bit cuttings, shavings, and other abrasive articles from a drilling mud that is passed through an oil or gas well drilling system (10) is provided that includes an overhead drilling system (23), a drill string (19) connected to the overhead drilling system (23), and a mud filter (26) for filtering the drilling mud, wherein the mud filter (26) is disposed within a drilling mud fluid passageway (8) that extends from the entry point of the drilling mud into the overhead drilling system and the entry point of the drilling mud into the drill string (19).

Description

technical field [0001] The present invention relates to an improved apparatus and method for filtering drill bit cuttings, waste cuttings and other abrasive matter from a drilling mud fluid passage in an oil or gas well drilling system as defined herein, and in particular to A mud filter in or connected to the drilling fluid passage of a pendant drilling, top drive drilling system, or power swivel. Background technique [0002] The drill string includes a joint of multiple threadably connectable drill rods, where each drill rod has a length of approximately 30 feet in length. One end of each drill rod has internal threads (the "box" end of the rod), and the opposite end of each drill rod has external threads (the "pin" end of the rod). A series of three thread-connected drill pipes is often referred to as a "table" of drill pipe. Each table has a length of approximately 90 feet. Multiple stands of ready-to-use drill pipe are typically stored vertically by the drill floor ...
