Split diffuser

Abstract

A jet pump splitter subassembly is provided having an interior chamber sized to allow a second diffusing cycle while directing the mixed fluid towards at least two exits in the jet pump housing. Preferably each of the exits are spaced uniformly about the periphery of the jet pump.

What is claimed is: 
     
         1 . A jet pump comprising:
 a housing,   a power fluid,   a wellbore fluid,   a mixing chamber,
 wherein the power fluid and the wellbore fluid combine into a mixed fluid. 
   an expansion chamber,   a splitter,   wherein the splitter forms the mixed fluid into at least a first and second stream.   
     
     
         2 . The jet pump of  claim 1  wherein, the splitter forms the mixed fluid into at least two approximately symmetric streams. 
     
     
         3 . The jet pump of  claim 1  wherein, the at least first and second streams are directed towards at least two ports in an exterior of the housing. 
     
     
         4 . The jet pump of  claim 1  wherein, the at least first and second streams are directed towards at least two ports wherein each port has a wing. 
     
     
         5 . The jet pump of  claim 1  wherein, the splitter is a cone. 
     
     
         6 . The jet pump of  claim 1  wherein, the splitter is in a splitter chamber,
 wherein the splitter chamber allows further expansion of the mixed fluid. 
 
     
     
         7 . The jet pump of  claim 7  wherein, the splitter is optimized to reduce turbulence within the splitter chamber. 
     
     
         8 . A method of forming a jet pump splitter assembly comprising:
 placing a splitter within a tubular,   forming at least a first and second port within the tubular,
 wherein the at least first and second ports are each located in a wall of the tubular above the splitter, 
   providing an adaptor to provide a flow path for a mixed fluid between a venture and the splitter.   
     
     
         9 . The method of forming a jet pump splitter assembly of  claim 8  wherein, the at least first and second ports are symmetric about the axis of the jet pump. 
     
     
         10 . The method of forming a jet pump splitter assembly of  claim 8  wherein, the splitter forms the mixed fluid into about symmetric streams. 
     
     
         11 . The method of forming a jet pump splitter assembly of  claim 8  further comprising a splitter chamber. 
     
     
         12 . The method of forming a jet pump splitter assembly of  claim 8  wherein, the splitter chamber allows for expansion of the mixed fluid. 
     
     
         13 . The method of forming a jet pump splitter assembly of  claim 8  wherein, the splitter is optimized to reduce turbulence within the mixed fluid streams. 
     
     
         14 . A jet pump comprising:
 a housing,   a power fluid,   a wellbore fluid,   a venturi,
 wherein the power fluid mixes with the wellbore fluid to form a mixed fluid. 
   a first expansion chamber,   a second expansion chamber,   at least two ports allowing a mixed fluid to exit the second expansion chamber.   
     
     
         15 . The jet pump of  claim 14  wherein, a splitter is located within the second expansion chamber. 
     
     
         16 . The jet pump of  claim 15  wherein, the splitter forms the mixed fluid into at least two approximately symmetric streams. 
     
     
         17 . The jet pump of  claim 15  wherein, the splitter is a cone. 
     
     
         18 . The jet pump of  claim 15  wherein, the splitter is optimized to reduce turbulence within the second expansion chamber. 
     
     
         19 . The jet pump of  claim 16  wherein, the at least two approximately symmetric streams are directed towards the at least two ports in an exterior of the housing. 
     
     
         20 . The jet pump of  claim 16  wherein, the at least two approximately symmetric streams are directed towards at least two ports wherein each port has a wing.
