    • A tool includes a housing between an outer wail and an inner wall that surrounds a longitudinal tool bore. First and second axially spaced ports connect the housing to the tool bore. An unlocking piston seals across the first port and an arming sleeve seals across the second port. A locking ring is held in place by a retaining ring and prevents the arming sleeve from sliding towards the unlocking piston to open the second port. An unlocking tool bore pressure at the first port moves the unlocking piston axially to displace the retaining ring and unlock the tool. A lower, arming tool bore pressure moves the arming sleeve in the unlocked tool to open the second port, and arms the tool. An actuating tool bore pressure, which is less that the unlocking pressure, actuates a valve piston via the open second port.

    • A re-closable toe sleeve is disclosed where the toe sleeve has a port allowing fluid access from the interior of the toe sleeve to the exterior of the toe sleeve. A burst disk is placed inside the port to prevent fluid access from the interior of the toe sleeve to the exterior of the toe sleeve. However upon the fluid in the interior of the toe sleeve reaching a predetermined level the burst disk is removed or otherwise modified to allow fluid access through the port. A sliding sleeve is placed within the toe sleeve so that the sliding sleeve can be moved to cover the port thereby preventing fluid access from the interior of the toe sleeve to the exterior of the toe sleeve or the sliding sleeve may be moved to uncover the port thereby allowing fluid access from the interior of the toe sleeve to the exterior the toe sleeve. The sliding sleeve is mechanically moved from the surface and is typically run into the well in the open position such that the port is uncovered by the sliding sleeve.
    • 公开了一种可重新闭合的脚趾套筒,其中脚趾套筒具有允许流体从脚趾套筒的内部进入到脚趾套筒的外部的端口。 爆破盘被放置在端口内以防止流体从脚趾套内部进入到脚趾套筒的外部。 然而,在脚趾套筒内部的流体达到预定水平时,爆破盘被移除或以其他方式进行修改以允许流体通过端口进入。 滑动套筒放置在脚趾套筒内,使得滑动套筒可以移动以覆盖端口,从而防止流体从脚趾套筒的内部进入到脚趾套筒的外部,或者滑动套筒可以移动以露出端口 从而允许流体从脚趾套筒的内部进入到脚趾套筒的外部。 滑动套筒从表面机械地移动,并且通常在打开位置进入井,使得端口被滑动套筒覆盖。
