Abstract

The present invention generally relates to a valve for use in an oilfield tool. The valve includes a valve body and a valve member disposed in the valve body. The valve member is movable between an open and closed position. The valve member includes an aperture therethrough. The valve further includes a pressure relief member disposed in the aperture, whereby at a predetermined pressure the pressure relief member will permit fluid communication. In another aspect, the invention provides an apparatus and a method for introducing fluid into a tubular.

Claims

1. A valve for use in an oilfield tool, the valve comprising:

a valve body;

a valve member disposed in the valve body and movable between an open and a closed position, the valve member including an aperture therethrough; and

a pressure relief member disposed in the aperture, whereby at a predetermined pressure the pressure relief member will permit fluid communication.

2. The valve of claim 1, wherein the valve member further includes a longitudinal bore therethrough providing fluid communication through the valve in the open position.

3. The valve of claim 2, further including a rotational member attached to the valve member to rotate the valve member in the valve body.

4. The valve of claim 3, wherein the rotational member causes the valve member to rotate between the open and closed position, whereby in the open position the longitudinal bore aligns with a passageway and in the closed position the aperture aligns with the passageway.

5. The valve of claim 1, further including a first and second seal member disposed at the upper end of the valve body.

6. The valve of claim 1, wherein the valve member in a closed position exposes the pressure relief member to a fluid pressure.

7. The valve of claim 6, wherein at the predetermined pressure the pressure relief member opens, thereby allowing fluid communication through the valve.

8. The valve of claim 1, wherein the valve member is a ball valve.

9. An apparatus to introduce fluid into a casing, the apparatus comprising:

a body having a bore therethrough; and

a valve disposed in the body for selectively controlling a fluid flow through the bore, the valve comprising;

a valve member movable between an open and closed position, the valve member including an aperture for providing selective communication through the valve in a closed position; and

a pressure relief member disposed in the aperture, whereby at a predetermined pressure the pressure relief member will permit fluid communication.

10. The apparatus of claim 9, wherein the valve further includes a rotational member attached to the valve member to rotate valve member between the open and closed position.

11. The apparatus of claim 10, wherein the rotational member causes the valve member to rotate to the open position when the apparatus is inserted in the casing and to the closed position when the apparatus is removed from the casing.

12. The apparatus of claim 11, wherein the valve member further includes a longitudinal bore therethrough for providing fluid communication through the bore in the open position.

13. The apparatus of claim 12, wherein the valve member in the closed position aligns the aperture with the bore, thereby exposing the pressure relief member to the fluid.

14. The apparatus of claim 13, wherein the predetermined pressure causes the pressure relief member to open, thereby permitting fluid communication through the bore.

15. The apparatus of claim 9, wherein the valve member is a ball valve.

16. A method of introducing fluid into a tubular, comprising;

locating an apparatus in the tubular, the apparatus comprising;

a body having a bore therethrough; and

a valve disposed in the body for selectively controlling a flow fluid through the bore, the valve including a valve member and a pressure relief member disposed in the valve member;

opening the valve in the apparatus;

pumping fluid through the apparatus;

introducing fluid into the tubular; and

removing the apparatus from the tubular.

17. The method of claim 16, wherein the valve member is movable between an open and a closed position.

18. The method of claim 17, wherein opening the valve allows fluid communication through the bore of the apparatus.

19. The method of claim 18, further including the step of closing the valve member allowing fluid to flow through the pressure relief valve.

20. The method of claim 19, wherein the predetermined pressure causes the pressure relief member to open, thereby permitting fluid communication through the bore.

21. A valve for use in an oilfield tool, the valve comprising:

a valve body; and

a valve member disposed in the valve body, the valve member movable between an open and a closed position, whereby in the closed position, the valve member will open at a predetermined pressure.
