摘要： A tracking receiver system (20) is used to track the progress of a downhole tool (10) along a subsurface path having a desired grade. The tracking receiver system is adapted to detect a reference line (22) originating from a reference line receiver (96) and to determine the position of the downhole tool (10) along a desired subsurface path relative to the reference line. In an alternative embodiment the tracking receiver system (20) may comprise a global positioning satellite system to provide information used to determine the position of the downhole tool relative to the desired subsurface path.
摘要翻译：跟踪接收器系统（20）用于沿着具有期望等级的地下路径跟踪井下工具（10）的进度。跟踪接收器系统适于检测源自参考线路接收器（96）的参考线（22），并且沿相对于参考线的期望地下路径确定井下工具（10）的位置。在替代实施例中，跟踪接收器系统（20）可以包括全球定位卫星系统，以提供用于确定井下工具相对于期望的地下路径的位置的信息。

摘要： A system and method for automatically drilling and backreaming a horizontal borehole underground. The system includes a horizontal drilling machine and a machine control system for operating the drilling machine. The machine control system has sensors and control circuits for monitoring and automatically controlling the functions of the drilling machine. The machine control system manages the power consumption of the drilling machine, the fluid dispensed during drilling and backreaming, the lengthening and shortening of the drill string, the tracking and recording of progress along a selected bore path, and the guiding of the downhole tool along the selected bore path. In a drilling operation the method involves identifying a selected bore path and automatically guiding the downhole tool along the selected bore path. In a backreaming operation the method involves connecting a backreamer and a utility line to the drill string and automatically pulling the utility line back through the borehole.
摘要翻译：一种用于自动钻井和回流地下水平钻孔的系统和方法。该系统包括一台水平钻机和一台用于操作钻机的机器控制系统。机器控制系统具有用于监测和自动控制钻孔机功能的传感器和控制电路。机器控制系统管理钻机的功耗，在钻井和回流期间分配的流体，钻柱的延长和缩短，沿着选定的钻孔路径的跟踪和记录，以及井下工具的引导所选孔径。在钻井操作中，该方法包括识别所选择的钻孔路径并沿所选择的钻孔路径自动引导井下工具。在回流操作中，该方法包括将后级联接器和公用设施线连接到钻柱，并自动地将公用事业线拉回井眼。
