    • A fracturing tool is used for hydraulically fracturing multiple stages of a well bore with treatment fluid. The tool includes a tubular housing retaining a longitudinally sliding sleeve which moves between a first position concealing fluid ports in the tubular housing and a second position in which the ports are uncovered. A deformable seat disposed in the sliding sleeve cooperates with an actuating member which is directed downwardly through a fracturing string locating a plurality of tools therein associated with respective stages of an isolated zone to sequentially uncover the fluid ports. Disposed in the fluid ports are burst plugs arranged to open when exposed to a threshold pressure. All uncovered burst plugs of the tools within the isolated zone can thus be sequentially uncovered and then opened when exposed to the threshold pressure to permit the treatment fluid to exit from the housing into the surrounding well bore.
    • 压裂工具用于利用处理流体水力压裂井眼的多个阶段。 该工具包括一个保持纵向滑动套筒的管状壳体,该套筒在管状壳体中的第一位置隐藏流体端口与端口未被覆盖的第二位置之间移动。 设置在滑动套筒中的可变形座椅与致动构件配合,该致动构件向下指向通过将多个工具定位在其中的压裂串,该多个工具与隔离区域的各个阶段相关联以顺序地露出流体端口。 设置在流体端口中的突发塞子被布置为当暴露于阈值压力时打开。 因此,隔离区域内的工具的所有未覆盖的爆裂塞可以被顺次地覆盖,然后当暴露于阈值压力时打开,以允许处理流体从壳体排出到周围的井眼中。

    • A downhole tool, such as a sliding sleeve, is operable with pressure applied against one of a plurality of plugs deployed in the tool. A sleeve can engage the deployed plugs and can move with the engagement. The sleeve extends in an absence of external support and releases the engaged plug. However, an indexing mechanism is operable between the sleeve and an insert in the tool. The indexing mechanism moves with the sleeve in response to the engagement with the deployed plugs and counts those engagements. In response to a predetermined count, the indexing mechanism forms the external support of the one deployed plug engaged in the sleeve and moves the insert with the pressure applied against the one deployed plug, which is engaged in the sleeve and supported by the indexing mechanism. For example, the insert can move open in the tool relative to a flow port communicating outside the tool.
    • 诸如滑动套筒的井下工具可操作地将压力施加到部署在工具中的多个插头中的一个上。 套筒可以接合所展开的插头并且可以随着接合而移动。 套管在没有外部支撑件的情况下延伸并释放接合的插头。 然而,分度机构可在套筒和工具中的插入件之间操作。 分度机构响应于与展开的插头的接合而与套筒一起移动并对这些接合进行计数。 响应于预定的计数,分度机构形成接合在套筒中的一个展开的插头的外部支撑件,并且使得插入件与施加在一个展开的插头上的压力移动,该插入件被接​​合在套筒中并由分度机构支撑。 例如,插入件可以相对于在工具外部通信的流动端口在工具中移动。

    • The invention relates to an insulation device for wells by controlled supply of the internal volume of an expandable sleeve placed on a casing, comprising a non-return valve placed in a passage which connects the internal volumes of the casing and of the sleeve and a three-way valve which switches a single time between an initial state in which a link connects the internal volumes of the casing and of the sleeve to expand the sleeve and a final state in which the link between the internal volumes of the casing and of the sleeve is interrupted, whereas a link is set up between the internal volume of the sleeve and an annular volume of the well, the three-way valve and the non-return valve forming, after switching, two non-return valves mounted in series and in opposite directions on the passage connecting the internal volumes of the casing and of the sleeve.

    • According to aspects of the present disclosure, systems and methods for a closed-loop speed/position control mechanism. An example system may include a housing and a planetary gearbox disposed within the housing, wherein a ring gear of the planetary gearbox is coupled to the housing, a sun gear of the planetary gearbox is coupled to a drive shaft, and a planetary carrier of the planetary gearbox is coupled to an output shaft. A controller may receive measurements from sensors proximate to the output shaft and use those measurements to transmit control signals to change the rotation of the drive shaft. In this way, the output shaft may be rotated independently of the housing by controlling the rotation of the drive shaft. In example systems, the output shaft may be a sonde or an offset mandrel coupled to a drill bit. The rive shaft may be coupled to a fluid-controlled controlled drive mechanism and rotation may be controlled by adjusting flow control valve. The closed-loop system may be used to set a target rotation speed of said output shaft or may be used to maintain the output shaft in a constant position or orientation despite housing rotation.
