    Abstract: In one embodiment, a method for drilling a wellbore includes injecting drilling fluid into a top of a tubular string disposed in the wellbore at a first flow rate. The tubular string includes: a drill bit tubular joints connected together, a longitudinal bore therethrough, and a port through a wall thereof. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The cuttings and drilling fluid (returns) flow to the surface via an annulus defined between the tubular string and the wellbore. The method further includes rotating the drill bit while injecting the drilling fluid; remotely removing a plug from the port, thereby opening the port; and injecting drilling fluid into the port at a second flow rate while adding a tubular joint or stand of joints to the tubular string. The injection of drilling fluid is continuously maintained between drilling and adding the joint or stand to the drill string. The method further includes remotely installing a plug into the port. A clamp specially adapted to carry out this method is also disclosed.

    Abstract translation: 在一个实施例中，用于钻井井的方法包括以第一流量将钻井流体喷射到设置在井筒中的管柱的顶部中。 管柱包括：连接在一起的钻头管状接头，穿过其中的纵向孔和通过其壁的端口。 钻井液离开钻头，并从钻头中携带钻屑。 切屑和钻井液（返回）经由管状柱和井筒之间限定的环形空间流到表面。 该方法还包括在注入钻井液的同时旋转钻头; 从端口远程移除插头，从而打开端口; 并且在第二流量下将钻井液注入到所述端口中，同时将管状接头或接头支架添加到所述管状管柱中。 在钻孔和向钻柱之间添加接头或支架时，连续地保持钻井液的注入。 该方法还包括将插头远程安装到端口中。 还公开了专门用于执行该方法的夹具。

    Abstract: Methods and apparatus enable reliable and improved isolation between two portions of a bore extending through a casing string disposed in a borehole. A downhole deployment valve (DDV) may provide the isolation utilizing a valve member such as a flapper that is disposed in a housing of the DDV and is designed to close against a seat within the housing. The DDV includes an operating mechanism for opening/closing the DDV. In use, pressure in one portion of a well that is in fluid communication with a well surface may be bled off and open at well surface while maintaining pressure in another portion of the casing string beyond the DDV.

    Abstract: A method for drilling a wellbore includes drilling the wellbore by advancing the tubular string longitudinally into the wellbore; stopping drilling by holding the tubular string longitudinally stationary; adding a tubular joint or stand of joints to the tubular string while injecting drilling fluid into a side port of the tubular string, rotating the tubular string, and holding the tubular string longitudinally stationary; and resuming drilling of the wellbore after adding the joint or stand.
