Pressure Booster for Rotary Steerable System Tool

Abstract

Aspects of the disclosure can relate to a drill assembly that includes a body for receiving a flow of drilling fluid. The body includes a crushing implement and/or a cutting implement and defines a nozzle that allows the drilling fluid to exit the body proximate to the crushing implement and/or the cutting implement. The drill assembly also includes an extendable displacement mechanism coupled with the body and powered by the flow of the drilling fluid. The drill assembly further includes a drive mechanism for driving a pump mechanism disposed in the body. The pump mechanism increases the pressure of a fraction of the flow of the drilling fluid, and the fraction of the flow of the drilling fluid is furnished to the extendable displacement mechanism.

What is claimed is:

 a body for receiving a flow of drilling fluid and comprising at least one of a crushing implement or a cutting implement, the body defining a nozzle allowing the drilling fluid to exit the body proximate to the at least one of the crushing implement or the cutting implement;   an extendable displacement mechanism coupled with the body and powered by the flow of the drilling fluid; and   a drive mechanism for driving a pump mechanism disposed in the body for increasing the pressure of a fraction of the flow of the drilling fluid, where the fraction of the flow of the drilling fluid is furnished to the extendable displacement mechanism.   
     
     
         2 . The drill assembly as recited in  claim 1 , wherein the drive mechanism comprises a turbine. 
     
     
         3 . The drill assembly as recited in  claim 2 , wherein the turbine comprises a multi-stage turbine. 
     
     
         4 . The drill assembly as recited in  claim 2 , wherein the turbine comprises at least one of an axial turbine or a radial turbine. 
     
     
         5 . The drill assembly as recited in  claim 1 , wherein the pump mechanism comprises a compressor. 
     
     
         6 . The drill assembly as recited in  claim 1 , wherein the pump mechanism comprises at least one of a roots blower pump, a piston pump, a screw feed pump, or a vane pump. 
     
     
         7 . The drill assembly as recited in  claim 1 , wherein the pump mechanism is positioned upstream from the drive mechanism. 
     
     
         8 . The drill assembly as recited in  claim 1 , wherein at least substantially the entire flow of drilling fluid through the body passes through the drive mechanism. 
     
     
         9 . A drill assembly comprising:
 a body for receiving a flow of drilling fluid and comprising at least one of a crushing implement or a cutting implement, the body defining a nozzle allowing the drilling fluid to exit the body proximate to the at least one of the crushing implement or the cutting implement;   an extendable displacement mechanism coupled with the body and powered by the flow of the drilling fluid; and   a pressure booster disposed in the body for increasing the pressure of a fraction of the flow of the drilling fluid, where the fraction of the flow of the drilling fluid is furnished to the extendable displacement mechanism.   
     
     
         10 . The drill assembly as recited in  claim 9 , wherein the pressure booster comprises a drive mechanism for driving a pump mechanism. 
     
     
         11 . The drill assembly as recited in  claim 10 , wherein the drive mechanism comprises a turbine. 
     
     
         12 . The drill assembly as recited in  claim 11 , wherein the turbine comprises a multi-stage turbine. 
     
     
         13 . The drill assembly as recited in  claim 11 , wherein the turbine comprises at least one of an axial turbine or a radial turbine. 
     
     
         14 . The drill assembly as recited in  claim 10 , wherein the pump mechanism comprises a compressor. 
     
     
         15 . The drill assembly as recited in  claim 10 , wherein the pump mechanism comprises at least one of a roots blower pump, a piston pump, a screw feed pump, or a vane pump. 
     
     
         16 . The drill assembly as recited in  claim 9 , wherein the pump mechanism is positioned upstream from the drive mechanism. 
     
     
         17 . The drill assembly as recited in  claim 9 , wherein at least substantially the entire flow of drilling fluid through the body passes through the drive mechanism. 
     
     
         18 . A method comprising:
 supplying at least a portion of a flow of drilling fluid to a nozzle proximate to at least one of a crushing implement or a cutting implement;   receiving the flow of drilling fluid at a drive mechanism for driving a pump mechanism to increase the pressure of a fraction of the flow of the drilling fluid;   furnishing the fraction of the flow of the drilling fluid to an extendable displacement mechanism powered by the flow of the drilling fluid.   
     
     
         19 . The method as recited in  claim 18 , wherein the drive mechanism comprises a turbine. 
     
     
         20 . The method as recited in  claim 18 , wherein the pump mechanism comprises a compressor.
