Well Drilling Assemblies and Methods

Abstract

Break out wrench assemblies are provided that can include: a pair of opposing arms linked by an actuator; at least one wheel assembly having an axle substantially normal to a surface of at least one of the opposing arms; and a power source coupled to the wheel. Methods for separating linked longitudinal sections are provided, the methods can include: providing at least two linked longitudinal sections; securing one of the two linked longitudinal sections; contacting another of the two linked longitudinal sections with at least one wheel; and powering the wheel to rotate the other of the sections in relation to the secured section.

1 . A break out wrench assembly comprising:
 a pair of opposing arms linked by an actuator;   at least one wheel assembly having an axle substantially normal to a surface of at least one of the opposing arms; and   a power source coupled to the wheel.   
     
     
         2 . The breakout wrench assembly of  claim 1  wherein each of the pair of opposing arms include a pivot point located along the length of each arm between the arms opposing ends. 
     
     
         3 . The breakout wrench assembly of  claim 2  wherein the pivot point includes an opening. 
     
     
         4 . The breakout wrench assembly of  claim 2  wherein the pivot point defines a bend in the length of each arm. 
     
     
         5 . The breakout wrench assembly of  claim 1  wherein the one opposing arm is configured to house the one wheel assembly, the housing having sidewalls extending from the one arm and extending to a roof. 
     
     
         6 . The breakout wrench assembly of  claim 1  further comprising another wheel assembly associated with the other opposing arm. 
     
     
         7 . The breakout wrench assembly of  claim 6  wherein the other opposing arm is configured to house the other wheel assembly, the housing having sidewalls extending from the one arm and extending to a roof. 
     
     
         8 . The breakout wrench assembly of  claim 6  wherein the other wheel assembly is a pair of wheels with each wheel having an individual axle aligned normal to the surface of the other arm. 
     
     
         9 . The breakout wrench assembly of  claim 8  wherein the other wheel assembly defines a recess. 
     
     
         10 . The breakout wrench assembly of  claim 1  wherein the power source is a hydraulic motor. 
     
     
         11 . A method for separating linked longitudinal sections, the method comprising:
 providing at least two linked longitudinal sections;   securing one of the two linked longitudinal sections;   contacting another of the two linked longitudinal sections with at least one wheel; and   powering the wheel to rotate the other of the sections in relation to the secured section.   
     
     
         12 . The method of  claim 11  wherein the linked longitudinal sections are linked via a thread engagement. 
     
     
         13 . The method of  claim 11  wherein the securing comprises actuating a first pair of opposing arms to secure at least one of the sections. 
     
     
         14 . The method of  claim 13  further comprising:
 actuating a second pair of opposing arms to secure at least another section; and 
 actuating a rotation of the second pair of opposing arms in relation to the first pair of opposing arms to unlock the one section from the other section. 
 
     
     
         15 . The method of  claim 14  wherein the powering the one wheel separates the one section from the other section. 
     
     
         16 . The method of  claim 11  further comprising vising the other section between a pair of wheel assemblies, one of which is the powered wheel assembly and each of the pair is associated with opposing arms. 
     
     
         17 . The method of  claim 16  further comprising actuating the opposing arms to vise the other section between the wheel assemblies. 
     
     
         18 . The method of  claim 11  wherein the longitudinal sections are sections of drilling pipe. 
     
     
         19 . The method of  claim 11  wherein the actuating is hydraulic actuation.
