Abstract
An improved lubricator valve arrangement for use within a wellbore to allow the passage of tools, such as perforating guns and the like, into the wellbore while it is live. The inclusion of two, independently controllable flapper-type safety valves within the lubricator valve will permit coordinated testing of fluid pressure both above and below the lubricator valve. The upper flapper valve includes a rotational flip-flap arm arrangement to positively open and close the upper flapper valve. The lower flapper valve is equipped with an integrated poppet-style pressure equalizing valve to allow the lower flapper valve to be opened more easily. The direction of opening of the flapper valves precludes or reduces the risk debris-related problems that might prevent or hinder opening of the flapper valves.
Claims
1. A lubricator valve for selectively closing off fluid flow within a production tubing string and for selectively passing a tool through the production tubing string, the lubricator valve comprising: a valve housing to be incorporated into a production tubing string; a first flapper valve within the housing having a first flapper member that is operable between open and closed positions to selectively close off fluid flow through the production tubing string; a second flapper valve within the housing having a second flapper member that is operable between open and closed positions to selectively close off fluid flow through the production tubing string; a flip-flap mechanism for selectively moving the first flapper member between the open and closed positions, the flip-flap mechanism comprising: an orientation sleeve that is disposed within the housing and rotationally moveable therewithin; and a flip-flap arm member extending between the orientation sleeve and the first flapper member, the arm mechanically moving the first flapper member to the closed position upon rotation of the orientation sleeve in a first direction and mechanically opening the first flapper member upon rotation of the orientation sleeve in a second direction that is opposite the first direction.
2. The lubricator valve of claim 1 further comprising a tubular member that is axially moveable within the valve housing, the tubular member having a shaped end to abut an axial side of the first flapper member in a flush, mating relation.
3. The lubricator valve of claim 1 wherein the second flapper member includes a pressure -equalizing valve for equalizing pressure across the second flapper member prior to moving said second flapper member to the open position.
4. The lubricator valve of claim 3 wherein the pressure-equalizing valve comprises a poppet-style valve that is actuated to equalize pressure across the second flapper member upon contact by an axial end of a flow tube.
5. The lubricator valve of claim 1 wherein the orientation sleeve is rotated with respect to the valve housing by contacting a shaped engagement surface on the orientation sleeve and camming the engagement surface to rotate the orientation sleeve.
6. The lubricator valve of claim 1 wherein the first and second flapper members are each secured to the valve housing by a hinge, and each of the flapper members is moved from a closed to an open position by pivoting the flapper member downwardly away from a closure seat so that debris atop the flapper member will not block opening of the flapper member.
7. The lubricator valve of claim 1 further comprising: a closing sleeve that is axially moveable with respect to the valve housing and having a shaped axial end to be selectively brought into flush, mating contact with a first axial side of the first flapper member upon axial movement of the closing sleeve with respect to the valve housing; and a flow tube that is axially moveable with respect to the valve housing and having a shaped axial end to be selectively brought into flush, mating contact with a second axial side of the first flapper member upon axial movement of the flow tube with respect to the valve housing. 21
8. A system for conducting a downhole operation from the surface into production tubing string of a live well, the system comprising: a) a lubricator valve for selectively closing off fluid flow within a production tubing string and for selectively passing a tool through a production tubing string, the valve comprising: a valve housing defining an axial bore for passage of fluid and tool through the valve housing; first and second flapper valves within the valve housing, each of the first and second flapper valves having valve seats and flapper members that are selectively moveable between a closed position, wherein the flapper member is seated upon the valve seat, and an open position, wherein the flapper member is pivoted away from the valve seat; at least one of the first and second flapper members being moved to an open position by pivoting of the flapper member downwardly and away from the valve seat; a flip-flap mechanism for selectively moving the first flapper member between the open and closed positions, the flip-flap mechanism comprising an orientation sleeve that is disposed within the housing and rotationally moveable therewithin, and a flip-flap arm member extending between the orientation sleeve and the first flapper member, the arm moving the first flapper member to the closed position upon rotation of the orientation sleeve in a first direction and opening the first flapper member upon rotation of the orientation sleeve in a second direction that is opposite the first direction; and b) a downhole tool for conducting an operation within the well, the tool being shaped and sized to pass axially through the lubricator valve. 22
9. The system of claim 8 wherein both of the first and second flapper members are moved to an open position by pivoting of the flapper member downwardly and away from the valve seat.
10. The system of claim 8 further comprising: a closing sleeve that is axially moveable with respect to the valve housing and having a shaped axial end to be selectively brought into flush, mating contact with a first axial side of the first flapper member upon axial movement of the closing sleeve with respect to the valve housing; and a flow tube that is axially moveable with respect to the valve housing and having a shaped axial end to be selectively brought into flush, mating contact with a second axial side of the first flapper member upon axial movement of the flow tube with respect to the valve housing.
11. The system of claim 8 wherein the downhole tool is a perforating gun.
12. The system of claim 8 wherein at least one flapper member incorporates an equalization valve for equalizing pressure across the flapper member prior to moving the flapper member to an open position, the equalization valve being actuated to equalize pressure by contact from an axially moveable tube within the lubrication valve.
13. The system of claim 8 wherein the orientation sleeve is rotated with respect to the valve housing by contacting a shaped engagement surface on the orientation sleeve and camming the engagement surface to rotate the orientation sleeve.
14. A method for conducting a downhole operation from the surface into a production 23
tubing string of a live well, the method comprising the steps of: installing a lubricator valve within a production tubing string, the lubricator valve having first and second flapper valves that are independently operable between open and closed positions to selectively block passage of fluid or tools through the lubricator valve; disposing the production tubing string within a wellbore with the first and second flapper valves in the open positions; closing the first flapper valve by engaging a lug on the first flapper member with a flip-flap arm member having a slot therein for receiving the lug and moving the lug along the slot to cause the first flapper member to move from an open to a closed position; pressure testing the lubricator valve from at least one axial direction; opening both of said first and second flapper valves; and disposing a downhole tool through the production tubing string and the lubricator valve to a point below the lubricator valve.
15. The method of claim 14 wherein the step of pressure testing the lubricator valve comprises alternately increasing pressure at two axial ends of the lubricator valve.
16. The method of claim 14 wherein the step of closing the first valve further comprises rotating an orientation sleeve within the valve housing to cause the lug to move along the slot.
17. The method of claim 14 wherein the step of closing the first flapper valve further comprises: closing the first flapper member; and urging shaped end portions into flush, mating contact with both upper and lower axial sides of the first flapper member to retain the first flapper member in the closed position. 24
18. The method of claim 17 wherein the shaped end portions are brought into contact with the upper and lower axial sides of the first flapper member by axially urging flow tube members within the lubricator valve using hydraulic fluid injection.
