摘要

The method includes installation in the well of high strength tubing, mechanical anchoring device, turning device, sealing device, deflector; running hydromonitor nozzle, wellbore trajectory control module, navigation system, work coil tubing section, flow re-distribution device, check valve and supply coil tubing section. By fluid supply into annulus between tubing and coil tubing and running coiled tubing, hydromonitor drilling of planned length of controlled radial channel in the formation is performed. Fluid with cuttings coming out the well through annulus between tubing and casing string, cleaned at surface and circulated back. After drilling, the work coil tubing section is retrieved from the formation and well circulation is performed until full carryover of cuttings. By mechanical turning device, the deflector is re-positioned to a different plane; the working cycle is repeated for the next radial channel. Milling of windows for all radial channels is performed beforehand during well preparation stage.
