FIELD: testing equipment.
SUBSTANCE: invention relates to the testing of hydraulic machines and is intended to measure the performance of submersible gas separators used in oil production. A method for testing the gas separator 1 on a gas-liquid mixture is proposed, including measuring the flow rates in the liquid supply lines 5 and gas 6 at the inlet to the gas separator 1, forming a gas-liquid mixture and feeding it to the base 2 of the gas separator, separation in the gas separator 1, diverting the flow of the gas-liquid mixture from the gas discharge holes 3 in the head of the gas separator through the casing 8 to an additional device 23 for separation of liquid and gas, removal of gas separated in the additional device 23 into the atmosphere, measurement of the flow rate of liquid and gas flows separated in the additional device 23, the discharge of a degassed liquid with a fixed free gas content into the main tank 14, calculation of the separation coefficient of the tested gas separator 1 based on measurements of liquid and gas flow rates. Throughout all tests, a constant pressure is maintained at the inlet to the gas separator, the supply of working fluid through the gas separator is set using a control valve 20 installed in the degassed liquid discharge line 4. For each mode with a given free gas content, a set pressure difference is established and maintained at the inlet to the gas separator and at the outlet of the gas discharge holes 3 in the casing 8, equal to the pressure difference in the column of the gas-liquid mixture outside a similar gas separator operating in the well, between the inlet to the gas separator and the gas discharge holes. A stand for testing gas separators on gas-liquid mixtures for the implementation of the described method is also proposed.
EFFECT: increase in the accuracy of calculations of the separation characteristics of the gas separator, the permissible volume content of free gas at the inlet to the gas separator.
