FIELD: oil and gas industry.
SUBSTANCE: when surveying a gas well, its head is equipped with a separator, a gas flow rate measuring device and a flow line for flame. Gas pressure and temperature is measured on the installed device and the well flow rate is determined based on performed measurements and structural characteristics of the device. In addition, the well head is equipped with an electric power plant generating electric power at combustion of produced gas. When surveying high-flow-rate wells, the electric power plant is installed between the gas flow rate measuring device and the flame line. When surveying low-flow-rate wells, the electric power plant is installed before the gas flow rate measuring device.
EFFECT: use of produced gas during survey of gas wells for generation of electric power.
