摘要： A method of operating a valve arrangement of a downhole apparatus comprising a tubular body having first and second ports in a wall thereof includes operating the valve arrangement from a locked first configuration, in which the first port is closed and the second port is closed, to a locked second configuration, in which the first port is open and the second port is closed, wherein the locked first configuration is an initial configuration of the valve arrangement. The method includes operating the valve arrangement from tile locked second configuration to a third configuration, in which the first port is closed and the second port is open.

摘要： A valve arrangement is for a downhole apparatus having a tubular body having first and second ports in a wall thereof. The valve arrangement comprises a valve member that comprises a first port associated with the first port of the tubular body; and a second port associated with the second port of the tubular body. The valve arrangement is configurable to be locked in a first configuration with the tubular body, such that the first port is closed and the second port is closed. The valve arrangement is configurable to be locked in a second configuration with the tubular body, such that the first port is open and the second port is closed. The valve arrangement is configurable to be locked in a third configuration with the tubular body, such that the first port is closed and the second port is open.

摘要： A valve arrangement is for a downhole apparatus having a tubular body having first and second ports in a wall thereof. The valve arrangement comprises a first valve arrangement associated with the first port and comprising a first valve; and a second valve arrangement associated with the second port comprising a second valve. The valve arrangement is configurable to lock in a first configuration with the tubular body, such that the first port is closed and the second port is closed; lock in a second configuration with the tubular body, such that the first port is open and the second port is closed; and lock in a third configuration with the tubular body, such that the first port is closed and the second port is open.

摘要： Downhole Apparatus and Method For Providing Zonal Isolation. There is provided a sandscreen joint (110) capable of providing zonal isolation. The ends of the portion of the (110) are capable of extension on activation of the sandscreen (110), including transition areas (135), which are coated with an elastomer sleeve (134). On activation of the sandscreen (110), the sleeve (134) is pushed out into contact with the bore wall and serves to isolate the zone on one side of the activated sleeve (134) from the zone on the other side of the sleeve (134). Thus, the provision of the sleeve (134) on the activated sandscreen (110) may prevent fluid from flowing axially along the bore between the bore wall and sandscreen. This may serve to protect the weave at the transition area (135), preventing axial flow through the transition areas (135).

摘要： A method comprises operating a first valve arrangement and a second valve arrangement from a locked first configuration, in which the first port is closed and the second port is closed, to a locked second configuration, in which the first port is open and the second port is closed. The method comprises operating the first valve arrangement and the second valve arrangement from the locked second configuration to a third configuration, in which the first port is closed and the second port is open; and moving the first valve arrangement to a third intermediate configuration between a second intermediate configuration and the third configuration, in which the first valve arrangement is locked, the second valve arrangement is locked and the first and second ports are closed.
