METHOD FOR DETERMINATION OF PRODUCTION RATE OF WELLS' PRODUCTION Russian patent published in 2008 - IPC E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: invention is referred to the field of measuring of quantity of fluid and gas in a gas-liquid mixture. It can be used both in a petroleum industry and in those production fields where it is necessary to metre quantity of fluid and gas in a two phase flow. It provides increase of functionality of panel measuring devices operating on fields by attachment to it of functions of gas and fluid gain measuring for gas-oil ratio definition at minor alteration of means and measuring technology. Essence of invention: method includes hole hooking up on measurement, separation of a well production and fluid accumulation in a metering tank with fluid and gas diversion lines of fluid and gas, measuring of temperature, a fluid and gas production rate. According to the invention a hole is hooked up serially on panel measuring devices, and for definition of a production rate of fluid and a gas at the barred line of diversion the gas diversion line is bridged. The pressure is defined and time of gas diversion line capping is fixed. Fluid accumulation with a pressure boost in a metering tank is continued. Simultaneously or in any succession fluid and gas diversion lines is opened. The pressure is defined and time of opening of first by turns lines and a gas gain in a metering tank and a fluid gain in a metering tank during its work with both bridged fluid and gas diversion lines is defined.

EFFECT: increase of functionality of panel measuring devices at minor alteration of means and measuring technology.
