Options of solution of oil well rate control problem

It is noted, that the problem of measurement under technological control of volume or mass of fluid or gas, produced by the well, technically con be s olved, using several options: measurement of single phase flows; preliminar y treatment of the flow by mixing. Reviewed ore flowmeters, which do not re quire special stimulation of the flow of the controlled medium. Presented a re necessary parameters of devices for measuring flow rate of liquid and ga seous phase in the mixture of oil, water and gas.
