摘要： A system and method for drilling horizontal directional boreholes with a continuous dual member drill string. A horizontal directional drilling machine is comprised of a flexible dual member drill string having a tubular outer member and an inner member rotatably disposed within the outer member. A downhole tool assembly and drill bit is connected to the downhole end of the inner member. The flexible drill string is stored in a coil on a reel or in a drum. At the uphole end of the drill string, a traction drive system provides thrust forces to advance and retract the drill string, and a rotary drive system rotates the inner member. The downhole tool assembly is steered by advancing the drill string with the traction drive and rotating the drill bit with the rotary drive.

摘要： Parallel drilling systems and methods suitable for drilling wells for steam-assisted gravity drainage (SAGD). In some method embodiments, a tilted-antenna tool gathers azimuthally- sensitive electromagnetic signal measurements. Such measurements enable accurate measurement of inter-well distance and direction, thereby providing the necessary information for drilling accurately-spaced wells having reduced vulnerability to 'short-circuits' that inhibit effective reservoir exploitation. In some other method embodiments, a tilted-antenna tool transmits azimuthally non-uniform signals as it rotates. The attenuation and azimuthal variation detected by one or more receivers enables accurate direction and distance determination. The transmitter and receiver antennas can in some cases be combined into a single tool, while in other cases the transmitters and receivers are placed in separate wells to increase detection range.
摘要翻译：用于蒸汽辅助重力排水（SAGD）钻井的平行钻井系统和方法。在一些方法实施例中，倾斜天线工具收集方位角敏感的电磁信号测量。这样的测量可以准确测量井间距离和方向，从而提供必要的信息，用于钻取精确间隔的井，从而降低了对“有效的储层开采”的“短路”的脆弱性。在一些其它方法实施例中，倾斜天线工具在其旋转时发送方位不均匀的信号。由一个或多个接收器检测到的衰减和方位角变化使得能够进行精确的方向和距离确定。在某些情况下，发射机和接收机天线可以组合成单个工具，而在其他情况下，发射机和接收机将放置在单独的井中，以增加检测范围。
