METHODS FOR CLEANING OUT HORIZONTAL WELLBORES USING COILED TUBING |
摘要 |
Methods for cleaning out horizontal wellbores using coiled tubing are provided for use during downhole operations. A coiled tubing having a bottom hole assembly is deployed into a horizontal wellbore. Fluid is circulated down the annulus of the wellbore and up the bottom hole assembly while the bottom hole assembly is moved upward at a selected rate and distance. This method may be used to remove downhole solids, such as formation sands and proppant. |
