    • A tool for selectively treating a wellbore with fluid that includes a tubing string having a sidewall defining an inner bore, the sidewall comprising a flow area having at least one fluid flow port that permits fluid flow through the sidewall. Fluid is prevented from flowing through the flow area when a closure is in a closed position. When in the open position, fluid flows through the flow area. An axial seal is connected to the closure to selectively close the inner bore against fluid pressure to apply the predetermined opening force to move the closure to the open position. A releasable connector connects the axial seal to the closure and a retrieval tool attachment releases the axial seal from the closure upon application of a predetermined release force by a retrieval tool.
    • 一种用于用流体选择性地处理井筒的工具,其包括具有限定内孔的侧壁的管柱,所述侧壁包括具有允许流体流过所述侧壁的至少一个流体流动端口的流动区域。 当封闭件处于关闭位置时,防止流体流过流动区域。 当处于打开位置时,流体流过流动区域。 轴向密封件连接到封闭件以选择性地关闭内孔以抵抗流体压力以施加预定的打开力以将封闭件移动到打开位置。 可释放的连接器将轴向密封件连接到封闭件,并且拾取工具附件在通过检索工具施加预定释放力时将封闭件的轴向密封件释放。

    • A modified planetary gear box and arrangement of the gear box with a drive motor permits electrical, optical or other types of cabling or wiring to be passed through the planetary gear box along its axis of rotation. The planetary gear box drives or rotates a reel of coiled tubing. Electrical, hydraulic, optical and other types of line for lowering into a well bore through the coiled tubing is passed through a passageway through the center of the planetary gear box, into one end of a hub of the reel, and then into the coiled tubing, which is injected into the wellbore. The other end of the hub of the reel is able to be connected to a swivel joint that can be connected to a pump for pumping fluid into the coiled tubing.
    • 改进的行星齿轮箱和齿轮箱与驱动马达的布置允许电气,光学或其他类型的布线或布线沿其旋转轴线穿过行星齿轮箱。 行星齿轮箱驱动或旋转一卷盘管。 电气,液压,光学和其他类型的线路,用于通过连续油管下沉到井眼中,穿过通过行星齿轮箱的中心的通道,进入卷轴的轮毂的一端,然后进入连续油管 ,其被注入井眼。 卷轴的轮毂的另一端能够连接到可连接到泵的旋转接头,以将流体泵入连续油管。
