摘要： A downhole tool (100) is responsive to passing objects and applied fluid pressure. A plugless valve (120) in the tool (100) is operable from an unobstructed condition to an obstructed condition unobstructing the tool's bore (104) to an obstructed condition obstructing the tool's bore (104) to the applied fluid pressure. An indexer (130) counts the objects passing through the tool's bore (104) and permits operation of the plugless valve (120) from the unobstructed to the obstructed condition in response to the counted number. The applied fluid pressure in the bore (104) obstructed by the plugless valve (120) can then communicate outside the tool (100) via at least one port (106). The plugless valve (120) can have a movable insert that moves relative to a flapper. The indexer (130) can use ratcheting dogs, collet, J-slot, electronic sensor, and other components to count the passing objects.

摘要翻译： 井下工具（100）响应于通过的物体和施加的流体压力。 工具（100）中的无阀阀（120）可从无障碍状态到阻塞状态操作，将工具的孔（104）阻挡到阻碍工具的孔（104）施加的流体压力的阻碍状态。 分度器（130）对通过工具的孔（104）的物体进行计数，并且允许无弹簧阀（120）响应于所计数的数量而从无障碍到阻碍状态的操作。 然后，由无阀阀（120）阻挡的孔（104）中施加的流体压力可以经由至少一个端口（106）在工具（100）外部通信。 无插阀（120）可以具有相对于挡板移动的可移动插入件。 分度器（130）可以使用棘轮犬，夹头，J型槽，电子传感器和其他部件来计算传球物体。
