jet facilities. SUBSTANCE: method comes to mounting of tubing with jet pump, packer and stem un well, pumping acid solution into tubing, packer releasing, forcing acid solution into formation and mounting of depression insert. Blocking insert with through passage channel is installed in jet plant before pumping in acid solution, and active medium feed and well medium pumped out channels in jet pump are closed by blocking insert. When forcing through acid solution, counterpressure is built in hole clearance. Prior to creating depression, blocking insert is taken out, check valve is installed and then depression insert is fitted in place blocking insert separating the tubing. When depression is built, products of acid treatment reaction are evacuated from formation and then depression insert and jet pump are taken out and pump for taking medium out of well is installed. EFFECT: improved efficiency of treatment of formation. 4 dwg
