Annotation:
The flow rate of oil, gas and water wells is not only the most important technological indicator of hydrocarbon fields the development, but also the necessary initial information for solving the problem of monitoring and managing the development. The quality of the decisions made is largely determined by measurements regularity and accuracy. The deposits geological structure and phase state, their geographical location forms the requirements to measuring devices. The main requirements include speed and instant response to changes not only in the flow rate itself, but also in the composition of the product, the ability to maintain performance at high values of the gas volume fraction, which is essential for oil and gas (gas and oil) fields and for oil fields at low bottomhole pressures. At the same time these measurements should be characterized by high accuracy and repeatability of results. All these requirements are met by the "Mera-MR.NOG" high-speed multi-phase metering unit developed by JSC "HMS Neftemash" based on the NetOil&Gas MPFM. The metering unit works steadily in various geological and physical conditions and under various well operation modes. The stability and quality of measurements are proved by field tests carried out to determine wells operational stability and the number of phases. A feature of the device under consideration lies in the preservation of the flow structure, which maximally corresponds to the natural flow mode. The high convergence of test results in real conditions allows confident use of multiphase flow meters for performing measurements in complicated mining-geological conditions, with possible complications in well operation in the form of free gas breakthrough from the gas cap. Obtaining high-quality information with continuous recording of flow rates and the amount of well production of each phase gives developers an effective instrument not only for controlling the technological parameters of a field development, but also for a deeper understanding of the processes occurring in the reservoir and for assessing the energy state of the deposit.
