摘要： A fluid cutting tool and method for perforating or severing tubular members from inside. The tool is especially suited for use with a rotational drive system, such as a downhole motor, to separate downhole structures, such as stuck production tubing. The cutting tool preferably takes the form of an elongate metal body with an open first end connectable to the end of a downhole motor. The downhole end of the tool may be conical. A fluid conduit within the body of the tool communicates with the fluid channel in the downhole motor. Ports in the sides of the tool body direct jets of cutting fluid out the side of the tool. The tool attached to the motor is fed downhole until the tool is at the desired location in the well. Then the motor is operated to rotate the tool while cutting fluid is pumped through it. This causes the jets of fluid to be directed at the inner surface of the production tubing (or other tubular structure). This process is continued until the tubing is perforated or severed, as needed.
摘要翻译：一种用于从内部穿孔或切断管状构件的流体切割工具和方法。该工具特别适用于诸如井下电动机的旋转驱动系统以分离井下结构，例如卡住的生产管道。切割工具优选采用细长金属体的形式，其具有可连接到井下电动机的端部的敞开的第一端。工具的井下端可以是圆锥形的。工具主体内的流体导管与井下电机中的流体通道连通。工具主体侧面的端口将切削液直接喷出工具的侧面。连接到电机的工具进入井下，直到工具位于井中所需的位置。然后在切割流体被泵送过程中，马达被操作以旋转工具。这导致流体射流被引导到生产管道（或其他管状结构）的内表面。根据需要，连续进行管道穿孔或切断。

摘要： Method and apparatus for drilling, completion, well workovers and well control, combining an integrated lifting unit and a coiled tubing unit, the method and apparatus permit running jointed pipe and coil tubing in combination, and standing multiple joints of pipe near the unit. The invention combines a hydraulic pipe hoisting system, pipe handling systems and pipe racking containment apparatus. A hydraulic workover jack is combined with a multifunction injector head and a standpipe for fluid circulation. The invention may also include a rotary table for rotating pipe and/or a rotating power swivel to allow fluid circulation during pipe rotation. Also included are a gin pole, a winching system for jointed pipe, and a traveling head with traveling slips and stationary slips to allow pipe movement in the well. Hydraulic systems allow insertion and extraction of tools in a work string. The apparatus includes spoolable drill pipe including a connector, multi-section reel with core, connection to reel for fluid circulation, reel drive mechanism and a pipe pulling capability.
