DEVICE FOR OIL AND GAS PARAMETRES RESEARCH IN DYNAMICS Russian patent published in 2010 - IPC E21B47/00 E21B47/12 

FIELD: oil-and-gas industry.

SUBSTANCE: geophysical equipment installs under a centrifugal pump, with a help of a drum and a loop, lapped with two-three laps on the drum and has a length commensurable to the research depth. Geophysical equipment and drum's drive connected with supply cables to the centrifugal pump power supply cable, which ensures the geophysical equipment constant operation and undisturbed data transfer to the surface. On the loop side opposite to the equipment fixed counterbalance or the second set of geophysical equipment, allowing to widen geophysical research ability twice. On the equipment and the counterbalance top ends designed end breakers for the drum drive automatic shut down, which corresponding signals to be received on the drum drive control panel, installed on the well head. The equipment move up and down in the research limit during the operation process. The equipment data to be transferred through the power cable to a receiver, installed on the well head.

EFFECT: wells equipped with centrifugal pumps research efficiency increase because of receiving well fluid real dynamic condition information.
