    • The present invention provides a method and apparatus for generating one or more than one physically detectable physical influence changes to control or manipulate a down hole device. The present invention intercepts existing control signals to various controllers on the rig and superimposes an encoded command on these existing control signals. The controllers comprise of motor drives, choke controllers (425), acoustic pulse generator/tracer injectors (423) and other controllers that are used to generate a physically detectable changes in the rig environment. The encoded command acting on existing or new controllers generates a perceptible change in a physical parameter such as a variation in drilling mud pressure (452), a variation in drill string rotation speed (430), a variation is weight on bit (424), generation of acoustic pulse (436), or a variation in tracer injection properties. The physical change is sensed by a downhole device and interpreted as information indicating to the downhole device that it is to execute a command or adjust an operating parameter.
    • 本发明提供一种用于产生一个或多于一个物理上可检测的物理影响变化以控制或操纵井下装置的方法和装置。 本发明拦截现有的控制信号到钻机上的各种控制器,并将编码的命令叠加在这些现有的控制信号上。 控制器包括电机驱动器,扼流器控制器(425),声脉冲发生器/示踪器注入器(423)和用于产生钻机环境中物理上可检测的变化的其它控制器。 作用于现有或新的控制器的编码命令产生物理参数的可察觉的变化,例如钻井泥浆压力(452)的变化,钻柱转速(430)的变化,变化是位(424)的重量, 产生声脉冲(436),或示踪剂注入性能的变化。 物理变化由井下装置感测,并被解释为向井下装置指示执行命令或调整操作参数的信息。

    • A drilling rig system including a man-machine workstation interface located in proximity to the drilling rig for providing to a single operator at substantially one location simultaneous operational access to drilling rig processes. The workstation includes an adjustable base 145 which allows swivelling through 270{ for example and an operator alcove 150 formed on the base in which an operator is positioned allowing for a substantially unobstructed view of the drilling rig. Adjustable forearm support panels 175 are formed on opposing sides of the operator alcove for supporting the forearms of the operator while positioned in the alcove. At least one display unit 155 is adjustably connected to the base and has a touch access screen adapted to allow the operator to monitor and control drilling rig processes. A plurality of discrete hand controls 160 are used for controlling predetermined drilling rig processes wherein at least one of the discrete hand controls is located on the forearm support panels (Fig 4). Preferably, an operator chair 165 is positioned in the alcove and is slideably connected to the base permitting seating and standing operation of the workstation. Data from multiple associated drilling equipment is integrated with data from a current drilling rig process to provide data to the operator on a process oriented basis displayed on said display units (Figs 6-12).
