FIELD: oil and gas industry. ^ SUBSTANCE: method includes lowering of the following using tubing: shank with plug, packer, lower bypass valves, located below and above holes of lower perforation interval in production string, and upper bypass valves, located below and above holes of upper perforation interval; also it includes activation of packers and wells operation. According to invention, above packer separating formations arranged below and above, there is lower remotely controlled bypass valve with plug installed. At the first stage flow distributor without its separating element is connected to lower remotely controlled bypass valve. Upper remotely controlled bypass valve is installed above upper bypass valve. Between lower and upper remotely controlled bypass valves in tubing of larger diameter there are pipes of smaller diameter installed. At the second stage their lower end is twisted in moveable hollow stock as a separating element which is passed inside flow distributor. Upper end of these pipes is connected to upper remotely controlled bypass valve. At that lower remotely controlled bypass valve is installed with possibility of cutout of fluid flow from lower perforation interval passed through moveable hollow stock and pipes of smaller diameter, and upper remotely controlled bypass valve is installed with possibility of cutout of fluid flow from upper perforation interval passed through annular space between tubing of larger diameter and pipes of smaller diameter. ^ EFFECT: improving accuracy of measurement of parameters of produced product extracted from separate production horizon, simplifying design, reducing man-hours and improving serviceability. ^ 7 cl, 4 dwg |
