Jet (Ejector) pump

SNI series:

• Record the inflow profile for controlled depressions (with a given value of depression) in wells with a static level of up to 900 (1100) m (at a working fluid injection pressure of at least 140 -160 atm., Flow rate of at least 4 l / s);
• Work when pumping the working fluid into the tubing or annulus;
• Remove reaction products from the bottomhole zone after chemical and physical treatments;
• Clean PZP from penetration products of drilling and cement mortars.

SNO series:

• To cause inflow from the reservoir in a wide range of depressions in wells with a static level of up to 1800 m (at a working fluid injection pressure of at least 200-220 atm, flow rate of at least 6 l / s);
• Carry out hydromechanical perforation and development for 1 STR;
• To conduct selective SCR when isolating untreated formations with a two-packer or three-packer arrangement;
• To influence the bottom-hole zone of the formation by physical impact (WDC - the method of cyclic depression-repression, vibration-wave effect on depression);
• Obtain GDI data before lifting the assembly from the well (when removing the jet pump insert);
• Pump with the creation of repression (push) the acid compositions into the reservoir and after that promptly remove the reaction products (the sleeve in the body overlapping the tubing-annulus message is used);
• To test the production casing and packer;
• Carry out hydrocarbon production and development (including with installation in shanks with a diameter of 102 mm or more).
