METHOD OF DATAWARE AND CONTROL OF FLUID WITHDRAWAL FROM OIL WELLS AND FACILITY FOR IMPLEMENTATION OF THIS METHOD Russian patent published in 2008 - IPC E21B43/00 E21B47/00 

FIELD: mining; engines and pumps.

SUBSTANCE: bottomhole apparatus with pressure, temperature and composition sensors, with resistivity and humidity meters is connected to cable of centrifugal pump and is arranged on section of geophysical cable under centrifugal pump before lowering of column. Further at lowering of production tubing the second bottomhole apparatus with pressure and temperature sensors is assembled at a specified distance above the centrifugal pump. Then communication channels are connected via the cable line with a well control system; they are assembled over producing reservoir in a borehole of vertical or inclined well. To commands of the control unit there are performed measurements of specified parameters and current time by means of a surface complex of apparatus including the control unit, a pumping assembly control station and a gauge unit of surface parameters. Obtained data are registered into memory, values are displayed on indication unit and data are transmitted via communication channels to the control unit to commands of which the surface control unit forms and transmits signals to the pump assembly control station facilitating optimisation of the process of well operation.

EFFECT: upgraded accuracy of controlled parameters with optimisation of control process and operation.
