Abstract
A ball catcher is adapted to be fluidly connected to a wellhead port to receive wellbore fluids and balls carried therewith. A diverter is fit to the catcher body and has a wellhead end positioned to intercept the fluid flow from the wellhead port so as to divert debris and balls carried therein into a ball recovery chamber.
The diverter has a bore in fluid communication with the flow outlet and the wellhead end has flow passages formed therethrough to the bore for receiving the fluid flow free of debris and balls and discharging the fluid flow from the catcher body.
The diverter and the ball recovery chamber can be connected to quick removal for replacement, repair or cleaning.
The diverter has a bore in fluid communication with the flow outlet and the wellhead end has flow passages formed therethrough to the bore for receiving the fluid flow free of debris and balls and discharging the fluid flow from the catcher body.
The diverter and the ball recovery chamber can be connected to quick removal for replacement, repair or cleaning.
Claims (25)
1. Apparatus for retrieving oversize debris and balls carried with a fluid flow from a wellhead port comprising:
a catcher body adapted to be fluidly connected to the wellhead port and having a flow outlet; and a diverter fit to the catcher body and having a wellhead end positioned to intercept the fluid flow from the wellhead port and to divert debris and balls carried therein into a ball recovery chamber, the diverter having a bore in fluid communication with the flow outlet and the wellhead end having flow passages formed therethrough to the bore for receiving the fluid flow free of debris and balls and discharging the fluid flow from the catcher body.
a catcher body adapted to be fluidly connected to the wellhead port and having a flow outlet; and a diverter fit to the catcher body and having a wellhead end positioned to intercept the fluid flow from the wellhead port and to divert debris and balls carried therein into a ball recovery chamber, the diverter having a bore in fluid communication with the flow outlet and the wellhead end having flow passages formed therethrough to the bore for receiving the fluid flow free of debris and balls and discharging the fluid flow from the catcher body.
2. The apparatus of claim 1 wherein the diverter is removeably fit to the catcher body.
3. The apparatus of claim 1 or 2 wherein the diverter is removeably fit through the flow outlet.
4. The apparatus of claim 1, 2 or 3 wherein some of the flow passages extend substantially in-line with the wellhead port.
5. The apparatus of any one of claims 1 to 4 wherein an annular chamber is formed between the catcher body and the wellhead end of the diverter, some of the flow passages being radial passages extending between the annular chamber and the bore.
6. The apparatus of any one of claims 1 to 5 wherein an annular chamber is formed between the catcher body and the wellhead end of the diverter, and wherein some of the flow passages being radial passages extending between the annular chamber and the bore; and some of the flow passages extend substantially in-line with the wellhead port.
7. The apparatus of any one of claims 1 to 6 wherein the wellhead end has a diverter face is angled away from the fluid flow for directing debris and balls into the ball recovery chamber.
8. The apparatus of claim 7 wherein the diverter face has a concave face having an axis oriented generally towards the ball recovery chamber.
9. The apparatus of claim 6 wherein the plurality of radial fluid passages in the wellhead end of the diverter are arranged in pairs of opposing passages for directing fluid to impinge each other within the bore.

17. The apparatus of claim 16 further comprising an annular chamber formed in the discharge outlet about the wellhead end of the diverter for receiving the fluid continuing to flow substantially along the flow path and about the diverter face.
18. The apparatus of claim 16 or 17 wherein the first velocity vector is substantially horizontal and wherein the ball recovery chamber is positioned below the flow path and below the diverter face.
19. The apparatus of claim 16, 17 or 18 wherein the diverter face is angled away from the fluid flow for directing debris and balls into the ball recovery chamber.
20. The apparatus of claim 19 wherein the diverter face has a concave face having an axis oriented generally downwards towards the ball recovery chamber.
21. The apparatus of any one of claims 16 to 20 wherein the plurality of fluid passages in the wellhead end of the diverter are arranged in pairs of opposing passages for directing fluid to impinge each other within the bore.
22. The apparatus of any one of claims 16 to 21 wherein the diverter is secured in the flow outlet with a quick connection.
23. The apparatus of any one of claims 16 to 22 wherein the diverter is two pieces comprising the wellhead end removeably coupled to the tail end.
24. The apparatus of any one of claims 16 to 24 wherein the wellhead end is formed of wear resistant material.
