    • A sliding sleeve has a sensor that detects plugs (darts, balls, etc.) passing through the sleeves. A first insert on the sleeve can be hydraulically activated by the fluid pressure in the surrounding annulus once a preset number of plugs have passed through the sleeve. Movement of this first insert activates a catch on a second insert. Once the next plug is deployed, the catch engages it so that fluid pressure applied against the seated plug through the tubing string can moves the second insert. Once moved, the insert reveals port in the housing communicating the sleeve's bore with the surrounding annulus so an adjacent wellbore interval can be stimulated. The first insert may also be hydraulically activated after a preset time after a plug has passed through the sleeve. Several sleeves can be used together in various arrangements to treat multiple intervals of a wellbore.
    • 滑动套管具有检测穿过套筒的塞子(飞镖,球等)的传感器。 一旦预设数量的插头已经穿过套筒,套筒上的第一插入件可以通过周围环空中的流体压力液压地激活。 第一个插入物的移动会在第二个插入物上激活捕获。 一旦下一个插头被部署,捕捉器就会啮合它,使得通过管柱对着座塞施加的流体压力可以移动第二插入件。 一旦移动,插入件就会露出外壳中的端口,将套管的孔与周围的环带连通,从而可以刺激相邻的井筒间隔。 在插头已经穿过套筒之后的预设时间之后,第一插入件也可以被液压地活动。 可以在各种布置中一起使用几个套筒来处理井眼的多个间隔。

    • A flow tool has a sensor that detects plugs (darts, balls, etc.) passing through the tool. An actuator moves an insert in the tool once a preset number of plugs have passed through the tool. Movement of this insert reveals a catch on a sleeve in the tool. Once the next plug is deployed, the catch engages the plug on the sleeve so that fluid pressure applied against the seated plug through the tubing string can move the sleeve. Once moved, the sleeve reveals ports in the tool communicating the tool's bore with the surrounding annulus so an adjacent wellbore interval can be stimulated. The actuator can use a sensor detecting passage of the plugs through the tool. A spring disposed in the tool can flex near the sensor when a plug passes through the tool, and a counter can count the number of plugs that have passed.
    • 流量工具具有检测通过工具的塞子(飞镖,球等)的传感器。 一旦预设数量的插头通过工具,执行器将刀片移动到工具中。 该插入物的移动显示工具上的套筒上的钩子。 一旦下一个插头被部署,该卡扣就接合套筒上的插头,使得通过管柱施加在座塞上的流体压力可以移动套筒。 一旦移动,套筒显示工具中的端口,将工具的孔与周围的环通信,从而可以刺激相邻的井筒间隔。 致动器可以使用通过工具的塞子的传感器检测通道。 设置在工具中的弹簧可以在插头通过工具时靠近传感器弯曲,并且计数器可以计数已经通过的插头的数量。
