FIELD: oil and gas industry.
SUBSTANCE: invention is referred to systems of oil and gas equipment automatic control and allows timely detecting of pre-emergency situations related to hydrate formation in gas equipment. According to the method gas pressure and temperature is measured periodically upstream and downstream gas equipment, gas flow rate through gas equipment or gas pressure drop is measured at orifice located in the gas flow passing through gas equipment. Then against measured values hydrate formation coefficient is formed for operating gas equipment and degree of hydrate formation is evaluated against deviation of this coefficient from the basic value determined in hydrate-free mode of gas equipment. In hydrate-free mode of gas equipment basic values of the above hydrate formation coefficient are used as technical state indicator for gas equipment.
EFFECT: method allows timely detecting of pre-emergency situations related to hydrate formation in gas equipment.
