EQUIPMENT COMPLEX FOR PRODUCTION OF HIGH-VISCOSITY OIL Russian patent published in 2012 - IPC E21B43/18 E21B37/06 

FIELD: oil and gas industry.

SUBSTANCE: equipment complex for production of high-viscosity oil comprises a lifting pipe with an oil pump drive installed inside and a mounted assembly from an oil pump, a perforated section of a pipe with a pump anchor and a well device. The well device is made in the form of a cylindrical vessel, in which there is a tight cavity and a circular chamber serially arranged with radial channels in its vessel. Besides, in the tight cavity there is a source of elastic oscillations of high frequency made as an ultrasonic converter of circular shape. The tight cavity along the assembly axis is equipped with a brace having an inner through channel leading to a circular chamber. The well device is connected with an electric cable to a ground power supply source. At the same time the complex is complemented with a ground pump, a line of liquid chemical reagent supply via an inner channel of the tight cavity brace into the circular chamber. The perforated channel of the pipe between the oil pump and the pump anchor is equipped with a hole for supply of a power supply cable and a chemical reagent supply line.

EFFECT: higher efficiency of ultrasonic treatment due to intensified additional chemical impact at oil into a casing pipe.
