Abstract: FIELD: oil and gas production. SUBSTANCE: invention is intended to raise oil and gas yield of productive pools of oil and gas wells by their exposure to energy of shock wave excited by electric discharge in fluid of bottom zone. Technical result of invention lies in intensified production of oil with less energy consumption thanks to effective action of electrohydraulic pulse shock wave on productive pool of well, in diminished overall dimensions of pulse source of energy and in reduced production cost. With this in mind electrohydraulic shock wave is generated in fluid in bottom zone of well by pulse discharges with the aid of capacitor discharge unit with spark gap sunk into well through casing string. Shock wave is excited from outside of casing string and for this capacitor discharge unit is brought out of limits of casing string through hole made in it. Shock wave generated in fluid is directed into oil-bearing soil to separate oil from soil. EFFECT: intensified oil output. 1 cl, 3 dwg

Abstract: FIELD: refrigerating engineering. 
     SUBSTANCE: proposed method includes setting the turbine outlet temperature and continuous measurement of pressure and temperature after air bleed stages of engine compressor. Air temperature and pressure at turbine inlet, temperature and pressure at turbine outlet and rotational speed of rotor are calculated by means of system modulating unit. Then, degree of reduction of pressure in turbine, present magnitude of corrected rotational speed of rotor and optimal magnitude of corrected rotational of rotor corresponding to maximum efficiency of turbine are determined. Braking torque of rotor is changed by acting on braking unit till optimal and present magnitudes of rotational speed of rotor get equal. In case rated magnitude of air temperature at turbine outlet exceeds preset magnitude, flow rate of purging air is decreased or increased till magnitudes get equal. When these temperatures are equal, consumption of fuel is determined for each bleed stage and is analyzed for obtaining minimum consumption of fuel. Then, air temperature and pressure at turbine inlet, temperature and pressure at turbine outlet and rotational speed of rotor are determined by means of sensors. According to results thus, obtained, above-mentioned parameters are determined and processes are repeated till optimal and present magnitudes of corrected rotational speed of turbine rotor and preset and measured magnitudes of air temperature at turbine outlet get equal after which actual consumption of fuel is determined.
