DESCRIPTION OF THE TYPE OF MEASURING INSTRUMENT Measuring installations "Satellite-Mass Meter NT.1"

Purpose of the measuring instrument

Measuring installations "Sputnik-Massometer NT.1" (hereinafter referred to as installations) are designed to measure the mass and mass flow rate of borehole fluid (crude oil) as part of an oil and gas mixture, the mass and mass flow rate of crude oil excluding water (oil), measurements of the volume and volume flow rate of free petroleum gas, reduced to standard conditions.

Description of the measuring instrument

The principle of operation of the units is based on measurements of the mass and mass flow rate of crude oil, mass and mass flow rate of crude oil without taking into account water, volume and volume flow rate of free petroleum gas reduced to standard conditions after separation in the separator.

The installations consist of a control and control unit (hereinafter referred to as BKU) and a technological unit (hereinafter referred to as BT).

Installations can be manufactured both in stationary and mobile versions, designed to connect a single well. In the manufacture of installations in the mobile version, the BT unit (a variant of the installations for connecting one well) and the BCU unit are installed in the body of a trailer or car, or on the chassis of a trailer or car.

The BKU includes a power cabinet, a measurement and information processing unit (hereinafter referred to as BIOI). In the embodiment of a stationary installation for connecting one well, the BIOI in an explosion-proof version can be installed in a BT.

The BT, depending on the design, includes measuring instruments (hereinafter referred to as SI): flow meters for mass and mass flow of liquid and gas, pressure, temperature, gas contamination, fire alarm sensors and equipment: protection against unauthorized access, separation tank (hereinafter referred to as EC) or pipe separator (hereinafter referred to as TC) , switching and regulating devices, pipelines with shut-off and control valves.

The BT, depending on the design, includes measuring instruments (hereinafter referred to as SI): flow meters for mass and mass flow of liquid and gas, pressure, temperature, gas contamination, fire alarm and equipment: protection against unauthorized access, separation tank (hereinafter referred to as EC) or pipe separator (further - TC), switching and regulating devices, pipelines with shut-off and control valves.

Depending on the design, configuration of measuring instruments and equipment, the units are available in the following versions:

  1. version 1 – with a mass liquid flow meter, a flow moisture meter in a liquid line and a mass gas flow meter in a gas line;
  2. version 2 – with a mass liquid flow meter, without a flow moisture meter in the liquid line and a mass gas flow meter in the gas line;
  3. version 3 – with a mass liquid flow meter, a flow moisture meter in a liquid line and a volumetric gas flow meter in a gas line;
  4. version 4 – with a mass liquid flow meter, without a flow moisture meter in the liquid line and a volumetric gas flow meter in the gas line;
  5. version 5 – with a volumetric liquid flow meter and a flow density meter of liquid in a liquid line and a volumetric gas flow meter in a gas line;
  6. - version 6 – with a mass flow meter of liquid/gas or with a volumetric flow meter of liquid/gas and a flow density meter of liquid on a common measuring line of liquid/gas;

IU can be manufactured both in stationary and mobile versions, designed to connect one well.

Installations in different versions measure the mass and mass flow rate of liquid, the mass and mass flow rate of dehydrated oil, the volume and volume flow rate of gas, given to standard conditions in automatic mode, taking into account:

  • values of water and oil density introduced into the BIOI program, measured by standardized methods in laboratory conditions;
  • corrections for pressure and temperature of the working medium;
  • gas content of the working medium;

The list of the main SI, which are completed with the execution of the installations, is given in Table 1. The measuring instruments included in the installation are determined based on the requirements of the questionnaire for the installation or the technical specification of the customer.

Table 1 is a list of the main SI, which are equipped with modifications of the plant versions.
