METHOD FOR MEASUREMENT OF WELL FLOW RATE AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1996 - IPC

FIELD: oil producing industry. SUBSTANCE: fluid separated in gas separating head is supplied through one of admission lines to piston type meter. Measuring piston, in this case, moves to the other end of the meter to displace fluid and to discharge pipeline. At the moment of filling of measurement compartment, the value of hydrostatic pressure of fluid is determined. Fluid is fed to the measurement compartment from the other side by changing direction of fluid flow. Number of portions of liquid and gas phases are counted and volume and mass fluid, volume and mass of oil and water mass are calculated with the help of the offered mathematic expression. Separated gas is directed to tube-piston unit of gas measurement, and measurement is carried out in the similar manner. Additionally measured is gas temperature at the moment of filling of measurement unit with gas and gas volume and mass are determined by the offered relation. To determine the well gas factor, the start of measurement of the next portion of fluid is combined with that of gas portion measurement. EFFECT: higher efficiency. 2 cl, 1 dwg
