Manufacturing of new metring units AGZU

Purpose of measuring device

The metering units "Sputnik-Massomer HT.1" (hereinafter referred to as units) are intended for metering mass and mass flow rate of a wellstream liquid (crude oil) in the oil-gas-water mixture, mass and mass flow rate of liquid without water (oil), volume and volume flow rate of associated gas at standard conditions. 

Description of measuring instrument

The operation principle of the units is based on measurements of mass and mass flow rate of the well fluid (crude oil) in the oil and gas mixture, the mass and mass flow rate of the liquid without water (oil), volume and volumetric flow rate of associated gas at standard conditions after separation

The units consist of control block (hereinafter - BKU) and  technological block (hereinafter - BT).

The units can be manufactured in both fixed and mobile (single well) modifications. During manufacturing units in the mobile modification, BT block (single well) and BKU control block are installed in the body of the trailer or car, or on the chassis of the trailer or car.

BKU control block includes a power cabinet, module of measurements and information processing (hereinafter - BIOI).

BT block, depending on the version, includes measuring instruments (hereinafter referred to as SI) of mass and mass flow rate of liquid and gas, volume gas flow meters in the gas line, water cut meter, pressure sensors, temperature, gas contamination, fire alarm and equipment: Protection against unauthorized access, separation vessel (hereinafter - ES), switching and control devices, pipes with shut-off and control valves.

Depending on the design, configuration of measuring instruments and equipment, the units are produced in four modifications:

- modification 1 - with a mass liquid flow meter, water cut meter in a liquid line and a mass gas flow meter in the gas line;

- modification 2 - with a mass liquid flow meter, without water cut meter in a liquid line and a mass gas flow meter in the gas line;

- modification 3 - with a mass liquid flow meter,  water cut meter in a liquid line and a volume gas flow meter in the gas line;

- modification 4 - with a mass liquid flow meter,  without water cut meter in a liquid line and a volume gas flow meter in the gas line;

Units of different modifications measure the mass and mass flow rate of the wellstream liquid, the mass and mass flow of dehydrated oil, the volume and volumetric flow rate of free gas at standard conditions in an automatic mode, taking into account:

– the values of water and oil density inputed in the BIOI data program and measured by standardized methods in laboratory conditions;

– pressure and temperature corrections of the fluid

– Fluid GOR




The list of basic measuring instruments which complement the units modifications is given in Table 1. The measuring instruments included in the unit are determined on the basis of the requirements from unit questionnaire or the technical specification from the customer.
