Apparatus and method for controlling the feed-in speed of a high pressure hose in jet drilling operations |
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.
