Condensate field of gas metering technology

】) Natural gas, gas condensate field measurement difficulties mainly on the moisture in the single well, should be considered in the design and selection of instruments pulsating flow, turndown,[link widoczny dla zalogowanych], and intermittent flow disturbance and temperament characteristics and the temperature, pressure, interference and other factors. Anti-dirt,[link widoczny dla zalogowanych], anti-disturbance ability of the orifice flowmeter and non-contact devices (ultrasonic flow meter) should be the preferred type of measuring instrument; (2) moisture meter has been used in single well 'with the amount of testing on components of the flow meter (such as: vortex flowmeter, turbine flow meter) operation can be optimized to reduce measurement error. Single well gas flow rate range for large, easy to produce pulsating flow problems, extend the single well measurement time, after a steady air flow to be measured; for gas condensate well production fluctuation range, over range Sui individual single well flow conditions, can consider the well measured concentration; for intermittent flow on the measurement errors caused by pipeline vibration can be considered to increase the flow rectifier front-end to increase stability or flow meter device to reduce vibration caused by measurement error; optimize the measuring instruments can reduce the cleaning cycle media measurement error caused by unclean; field experience should also be explored under optimal temperature and pressure compensation coefficient, reducing individual well measurement error caused by temperature difference. (3) can meet the production of measuring instruments, instruments should be based on cost, installation conditions and other factors optimized selection. Such as the precession vortex flowmeter vortex flowmeter and temperament are suitable for clean, high precision measurement of the internal field measurement, but before the precession vortex flow meter straight pipe requirements (10D) than the first vortex flowmeter straight pipe requirements (20D) is low, wide range of relatively vortex flowmeter, vortex flowmeter can be no filter before, and vortex precession flowmeter to be installed before the filter, therefore, two flow meters is different, conditions for selection to be based on-site installation and instrumentation cost decision. (4) gas condensate field in the internal gas treatment station to ask temperament clean, stable gas (less disturbance), moderate accuracy requirements, natural gas measurement instruments can be optimized with data integration, Totalizer, remote intelligent features such as vortex flowmeter, rotating into the vortex flow meters, turbine flow meter. (5) the transfer of dry gas products can be optimized selection of measurement instruments and high precision measurement, easy operation, fouling ability, convenient orifice flowmeter test. Non-contact ultrasonic flow meter orifice flow meter, following after the second choice, but need to test more difficult to solve their problems. References [1] written so much.
