摘要： A method and apparatus for selectively reciprocating a downhole device in a wellbore relative to an upper portion of production tubing, so that the upper portion of production tubing does not need to be lifted to operate the downhole device. A shift tool between the upper production tubing and the deflector assembly is designed to lift a deflector assembly independently of the upper production tubing. The shift tool is operated by pressurized fluid delivered from the surface, for example with a fluid-delivery device on the end of coiled tubing lowered through the production tubing.
摘要翻译：一种用于相对于生产管道的上部选择性地将井下装置往复运动的方法和装置，使得生产管道的上部不需要提升以操作井下装置。上部生产管道和偏转器组件之间的换档工具被设计成独立于上部生产管道提升偏转器组件。换档工具由从表面输送的加压流体操作，例如通过在连续油管的端部通过生产油管下降的流体输送装置来操作。

摘要： A jetting hose is conveyed downhole retracted on the end of a tubing string (coiled tubing) for jetting lateral boreholes from a main wellbore. The apparatus allows the operator to sense the speed at which the jetting hose and nozzle are penetrating the formation and adjust the coiled tubing feed-in rate accordingly, optimizing both the direction and length of the lateral borehole relative to the main wellbore.

摘要： A jetting nozzle for forming boreholes or for cleaning out other tubular formations has a vibration-inducing mechanism that maximizing penetration rates and expands the diameter of the boreholes. The vibration-inducing mechanism can be an internal turbine responsive to the flow of pressurized jetting fluid through the nozzle. The nozzle has forward openings defining a voraxial spray pattern for the forward-directed jetting portion of the fluid exiting the nozzle. The nozzle can also have a pointed end that is adapted to penetrate the formation. The vibration also reduces friction between the fluid supply hose and the borehole being jetted through the formation by the nozzle. A system for forming boreholes with the jetting nozzle and a method of forming boreholes is also disclosed.
