DEVICE FOR MEASURING FLOW RATE OF OIL WELLS Russian patent published in 2019 - IPC E21B47/10 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to equipment used in oil industry and is intended for measuring and registering oil wells products. Device comprises a gas separator with a float associated with a gas gate on a gas line, communicating gas separator with a common line, connected to the controller flow meter, flow rate regulator installed on the line connecting gas separator with common line, with possibility of their fixation in two extreme positions "open" or "closed". At the same time pressure gauges connected to controller are installed on gaseous line, at that gaseous shutter on gas line and float of gas separator are connected by means of lever-spring mechanism with possibility of fixation of gaseous valve position "open" or "closed". At the same time, the gas flap is equipped with sensors of the open or closed position of the fixed volume of the gas separator of the liquid phase limited by the lower and upper levels determined by positions of the float, which are connected to the controller. At that, liquid line is connected through gas line with common line after gas shutter in front of flow meter, at that liquid line is equipped with liquid shutter with lever-spring mechanism connected with float of gas separator with possibility of fixing liquid damper in interconnected positions with gas shutter "open" or "closed". Liquid flap is equipped with fixed position sensors of "open" or "closed" position of gas separator of liquid phase bounded by lower and upper levels defined by positions of float.

EFFECT: technical result consists in improvement of quality and efficiency of measurement of flow rate of oil wells and in creation of reliable device with selection of optimum composition of measuring devices.
