METHOD OF DELIVERING EQUIPMENT AT COILED TUBING TO SPECIFIED INTERVAL OF MULTIHOLE PRODUCTION WELL AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC E21B23/00 E21B47/01 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to oil and gas producing industry, namely to the method of equipment delivery to the specified interval of multi-hole well and device for its implementation. In the course of method implementation the deflectors oriented from the well mouth are installed at the column of tubing, the equipment is lowered to the specified interval of the well and is delivered from column of tubing to the side hole in condition of closed access to the tubing interval located below or the equipment is lowered to the tubing column interval located below in condition of closed access to the side hole. The deflector installed at tubing is used as device. Deflector consists of hollow rotating housing equipped with lateral window and guiding element that provides coiled tubing passing to the side hole of the well or tubing interval located below.

EFFECT: due to the elimination of necessity to draw tubing column in advance the treatment and geophysical researches performance in multi-branch wells is simplified.
