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, wherein the valve member is movable to an open position when the valve is inserted in a wellbore tubular and to a closed position when the valve is removed from the tubular;
- an aperture formed in the valve member, the aperture providing fluid communication through the valve in the closed position;
- and
- a pressure relief member disposed in the aperture, the pressure relief member preventing fluid communication through the valve in the closed position, whereby at a predetermined pressure the pressure relief member permits 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 position when the apparatus is inserted into the casing and a closed position when the apparatus is removed from the casing, the valve member including an aperture for providing selective communication through the valve in the closed position, and
- a pressure relief member disposed in the aperture, whereby at a predetermined pressure the pressure relief member permits 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, wherein at a predetermined pressure the pressure relief member opens;
- opening the valve in the apparatus upon insertion into the tubular;
- pumping fluid through the apparatus;
- introducing fluid into the tubular;
- removing the apparatus from the tubular;
- and
- closing the valve and exposing the pressure relief member to fluid.
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 a closed position, the valve member includes a longitudinal bore therethrough for providing fluid communication through the bore in the open position and an aperture for providing selective communication through the bore in the closed position;
- a pressure relief member disposed in the aperture, whereby at a predetermined pressure the pressure relief member will permit fluid communication through the bore;
- and
- a rotational member attached to the valve member to rotate the valve member to the open position when the apparatus is inserted into the casing and to the closed position when the apparatus is removed from the casing.
A method of introducing fluid into to 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 movable between an open and a closed position and a pressure relief member disposed in the valve member;
- opening the valve to allow fluid communication through the bore of the apparatus:
- pumping fluid through the apparatus;
- introducing fluid into the tubular;
- removing the apparatus from the tubular;
- and
- closing the valve member and allowing fluid to contact the pressure relief member, wherein a predetermined pressure causes the pressure relief member to permit fluid communication through the bore.
