Rod Guide With Discharge Deflector

Abstract

A downhole sucker rod pump including a deflector configured to deflect fluid including solids from discharging against the inner wall of well tubing. The sucker pump deflector is configured to deflect discharged fluid upwardly in the well tubing, parallel to the inner wall of the well tubing to prevent abrasion. In one exemplary embodiment, the deflector may comprise a sleeve configured to be attached to the top of the sucker pump, such that fluid is discharged against an inner wall of the sleeve and directed upwardly. The sleeve may be threaded and attached to a threaded circumference of the top of the sucker pump.

1 . A downhole well pump for insertion in a downhole well tubing, comprising:
 a well pump including a pump barrel and plunger disposed therein configured to be placed within a stationary downhole well tubing having an inner wall, the pump barrel having an outer diameter and a discharge guide configured to guide the plunger and having at least one opening, the well pump configured to draw fluid from under the well pump and expel the fluid, laterally through the at least one opening and toward the inner wall of the well tubing;   a deflector coupled to an upper portion of the pump barrel and not completely encompassing the discharge guide, the deflector configured to deflect and change a direction of the fluid as it is expelled from the at least one opening of the discharge guide to prevent abrasion of the well tubing inner wall proximate the at least, one opening, wherein the deflector has an outer diameter no greater than the pump barrel outer diameter.   
     
     
         2 . The downhole pump as specified in  claim 1  wherein the deflector comprises a sleeve. 
     
     
         3 . The downhole pump as specified in  claim 2  wherein the deflector comprises, a cylinder. 
     
     
         4 . The downhole pump as specified in  claim 1  wherein the deflector is threadably secured to the upper portion of the pump barrel. 
     
     
         5 . The downhole pump as specified in  claim 4  wherein the upper portion of the pump barrel comprises a first threading, and the deflector comprises a second threading configured to threadably secure to the pump barrel first threading. 
     
     
         6 . The downhole pump as specified in  claim 2  wherein the sleeve and the pump barrel have a common outer diameter. 
     
     
         7 . The downhole pump as specified in  claim 1  wherein the discharge guide has a shoulder including the at least one opening. 
     
     
         8 . The downhole pump as specified in  claim 7  wherein the pump barrel has threading defined below the shoulder. 
     
     
         9 . The downhole pump as specified in  claim 7  wherein the discharge guide has a plurality of openings defined in the shoulder. 
     
     
         10 . The downhole pump as specified in  claim 2  wherein the sleeve covers the at least one opening. 
     
     
         11 . A system, comprising:
 a stationary well tubing having an inner wall and configured to be disposed in the earth;   a well pump including a pump barrel and a plunger disposed therein placed within the stationary well tubing, the pump barrel having a discharge guide configured to guide the plunger and having at least one opening, the well pump configured to draw fluid from under the well pump and expel the fluid laterally through the at least one opening and toward the inner wall of the well tubing; and   a deflector coupled to an upper portion of the pump barrel and not completely encompassing the discharge guide, the deflector configured to deflect and change a direction of the fluid as it is expelled from the at least one opening of the discharge guide to prevent abrasion of the well tubing inner wall proximate the at least one opening, wherein the deflector has an outer diameter no greater than the pump barrel outer diameter.   
     
     
         12 . The system as specified in  claim 11  wherein the deflector comprises a sleeve. 
     
     
         13 . The system as specified in  claim 12  wherein the deflector comprises a cylinder. 
     
     
         14 . The system as specified in  claim 11  wherein the deflector is threadably secured to the upper portion, of the pump barrel. 
     
     
         15 . The system as specified in  claim 14  wherein the upper portion of the pump barrel comprises a first threading, and the deflector comprises a second threading configured to threadably secure to the pump barrel first threading. 
     
     
         16 . The system as specified in  claim 12  wherein the sleeve and the pump barrel have a common outer diameter. 
     
     
         17 . The system as specified in  claim 11  wherein the discharge guide has a shoulder including the at, least one opening. 
     
     
         18 . The system as specified in  claim 17  wherein the pump barrel has threading defined below the shoulder. 
     
     
         19 . The system as specified in  claim 17  wherein the discharge guide has a plurality of openings defined in the shoulder. 
     
     
         20 . The system as specified in  claim 12  wherein the sleeve covers the at least one opening.
