    • A differential fill valve assembly for application in float collars or shoes in well casing. The valve assembly comprises a back pressure flapper valve disposed within a substantially tubular upper housing, and a lower housing containing an activating sleeve slidably disposed therein above a double flapper valve assembly. The activating sleeve initially extends into the upper housing to a sufficient extent to maintain the flapper valve in an open position; the activating sleeve is maintained in this position through use of shear pins, by which it is secured to the lower housing. The double flapper valve comprises a first flapper responsive to pressure below the valve assembly, and a second flapper responsive to force applied from above. A tripping ball is dropped to seat in the activating sleeve when it is desired to release the back pressure flapper valve; pressure applied on the ball moves the activating sleeve downward, releasing the back pressure flapper valve and swinging the double flapper valve assembly out of the flow path through the differential fill assembly, after which the tripping ball exits the bottom of the assembly. A lock ring maintains the activating sleeve in its lower position, while a shear screw riding in a longitudinal channel in the lower housing prevents rotation of the activating sleeve during its longitudinal movement prior to its contacting the double flapper valve assembly.
    • 一种用于应用于井套管中的浮子环或鞋的差压填充阀组件。 阀组件包括设置在基本上管状的上壳体内的背压挡板阀,以及容纳可滑动地设置在双挡板阀组件上方的致动套筒的下壳体。 起动套筒最初延伸到上壳体足够的程度以将挡板阀保持在打开位置; 激活套筒通过使用剪切销保持在该位置,由此固定到下壳体。 双瓣阀包括响应于阀组件下方的压力的第一挡板和响应于从上方施加的力的第二挡板。 当需要释放背压挡板阀时,跳闸球落到活动套筒中, 施加在球上的压力使致动套筒向下移动,释放后压挡板阀并且使双挡板阀组件从流动路径摆动通过差速填充组件,之后脱扣球离开组件的底部。 锁定环将启动套筒保持在其下部位置,而在下部壳体中的纵向通道中的剪切螺钉阻止致动套筒在其双重挡板组件接触之前的纵向移动期间的旋转。

    • A remote-controlled tubing sleeve window for access to a lateral wellbore of a multilateral well. The tubing sleeve window has a tubular body portion that defines a side port that is sufficiently-sized to allow a well tool to pass. A sleeve is received in the tubing body portion such that it can reciprocate within the body portion. The sleeve is responsive to a remote command such that a side window defined in the sleeve can be substantially-aligned with the side port in an open relation such that a well tool can pass through said substantially-aligned side window and side port. A position sensor is also provided to sense a displacement of the sleeve with respect to the body portion.
    • 用于进入多边井的侧井筒的遥控油管套筒窗口。 管套筒窗口具有管状主体部分,其限定了足够尺寸以允许井工具通过的侧面端口。 套筒容纳在管体部分中,使得其能够在主体部分内往复运动。 套筒响应于远程命令,使得限定在套筒中的侧窗可以与侧端口以开放的关系基本上对准,使得井具可以穿过所述基本对齐的侧窗和侧端口。 还提供位置传感器来感测套筒相对于主体部分的位移。

    • An apparatus (60) for actuating a well tool (148) in a wellbore includes a downhole robot (62) that provides for locomotion within the wellbore (144). A pressure control member (64) having a deployed position is operably associated with the downhole robot (62). An engagement mechanism (66) is operably associated with the downhole robot (62) and releasably engages with the well tool (148) such that when the engagement mechanism (66) engages the well tool, the pressure control member (64) is in the deployed position and a differential pressure is created across the pressure control member (64), the downhole robot (62) transmits a longitudinal force to actuate the well tool (148).
    • 用于致动井眼中的井具(148)的装置(60)包括提供在井筒(144)内运动的井下机器人(62)。 具有展开位置的压力控制构件(64)与井下机器人(62)可操作地相关联。 接合机构(66)与井下机器人(62)可操作地相关联并且可释放地与井工具(148)接合,使得当接合机构(66)接合井工具时,压力控制构件(64)处于 在压力控制构件(64)的两端形成压差,井下机器人(62)传递纵向力来致动井工具(148)。
