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.
Claims21
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.
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.
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.
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.
