Automated group metering unit (AGZU)

Price from: $ 1

The measurements performed by the installation comply with the requirements of GOST R 8.615-2005 for performing measurements on individual wells. Purpose of the automated metering unit: Automated metering units are designed for periodic measurement by the method of direct and indirect measurements of the amount of crude oil and free petroleum gas produced from oil and gas wells and further hardware – software processing of measurement results for the purpose of their accumulation, archiving and ensuring transmission to the telemetry system via communication channels established by users. liquid and gas of the following models: mass flow meters MICRO MOTION, series F, CMF, T, R DN 15 mm – 150 mm; mass flow meters PROMASS DN 8 mm – 250 mm; mass flow meters ROTAMASS, modifications RCCS, RCCT, RCCF; mass flow meters SFC; flow rate Mass flow meters MASSFLO. It is allowed to use other models of flow meters that meet the following conditions: Availability of the Type Approval Certificate of the measuring instrument. Ensuring the stated measurement limits. Ensuring the permissible relative measurement error of the parameters as part of the measuring unit in accordance with GOST R 8.615-2005. Switching of wells in the units. is carried out in one of the ways: Three-way ball valves with electric drives; multi-way switch of wells PSM. Separation of well production into gas and liquid (oil + water) is carried out by oil and gas separators. The number of wells connected to the installation is from 1 to 14 pcs. Those. specifications The nominal value of the mass average daily consumption of crude oil, depending on the version, t / day. from 1 to 300 Nominal value of the volumetric average daily gas consumption, m3 / day, (reduced to standard conditions) up to 2,500,000 Working pressure, MPa up to 16 Number of connected wells, pcs. from 1 to 14 Diameter of connecting pipelines, mm, not less than 50 Limits of permissible relative measurement error according to GOST 8.615-2005 – mass of crude oil,% ± 2.5 – volume of free petroleum gas,% ± 5 – mass of crude oil excluding water, with content water in oil in volume fractions,%, up to 70% ± 6 from 70 to 95% ± 15 over 95% In accordance with the certified MVI Power supply parameters of electrical circuits – alternating current type – voltage, V 380/220 – permissible voltage deviation,% from -15 up to + 10- AC frequency, Hz 50 + 1- power consumption, kW, no more than 10 Climatic conditions- ambient temperature, ˚С from 5 to 90- ambient temperature, ˚С from 5 to 90- content of sulfur compounds in mass fraction,%, not more than 3- hydrogen sulfide content, volume,%, not more 2- water content in liquid, volume fraction,% from 0 to 100- content of mechanical impurities, g / l, not more than 5- class of an explosive zone of a technological room В-1А- class of explosive zone non-explosive automation unit Overall dimensions of the installation Process room length, mm from 3135 to 6170 width, mm 3000 height, mm 3830 weight, kg from 3500 to 7200 Automatic unit length, mm 2000 width, mm 2850 height, mm 2735 weight, kg 1160
