20120043075 | METHOD AND ASSEMBLY FOR RECOVERING OIL USING ELASTIC VIBRATION ENERGY - A method and assembly for recovering oil using elastic vibration energy involves placing a downhole apparatus in a well, which downhole apparatus is connected to aboveground power supply units and contains an ultrasonic transducer that provides for the generation of high frequency elastic vibrations, exciting elastic vibrations of different frequencies and then repeatedly applying the elastic vibrations to the oil formation, wherein both high and low frequency vibrations are applied to the formation. The low frequency vibrations are generated with the aid of an electric pulse device which is connected to an aboveground power supply and includes the following electrically interconnected components: a charger, a unit of energy storage capacitors, a discharge unit with electrodes, and two switching devices. The method and assembly make it possible to recover oil from depths of over 2000 meters and to act effectively on the formation being treated. | 02-23-2012 |
20150075769 | SET OF EQUIPMENT FOR EXTRACTING HIGHLY VISCOUS OIL - A set of equipment for extracting highly viscous oil comprises a pump-compressor string with an oil-pump drive placed therewithin and an arrangement consisting of an oil pump, a perforated string section with a pump anchor, and a downhole tool, which is in the form of a cylindrical body, mounted consecutively on the mentioned string. A hermetic cavity and an annular chamber with radial channels are arranged consecutively in the mentioned body. A high-frequency elastic-oscillation source in the form of an ultrasonic converter is arranged in the hermetic cavity of the body. The hermetic cavity along the axis of the arrangement is provided with a tie bar having an internal through channel leading into the annular chamber. A distributing device in the form of a movable bushing is mounted on the external surface of the body. The downhole tool is connected by an electric cable to an above-ground electric power source. The set is additionally provided with a storage tank containing a reagent, a pump and a control valve which are arranged above ground and are interconnected by a pipeline, and with a line for feeding the liquid chemical reagent through the internal channel of the tie bar of the hermetic cavity into the annular chamber of the downhole tool. | 03-19-2015 |
20150218911 | DEVICE FOR DECOLMATATION OF THE CRITICAL AREA OF EXPLOITATION AND INJECTION WELLS - The device for the decolmatation of the critical area of exploitation and injection wells includes a generator of electromagnetic pulses of resonant frequency, which is equipped with a controller (not depicted), and a coaxial cable which connects the generator to a downhole instrument, in which at least two converters for converting electromagnetic energy into mechanical energy are arranged, the converters operating at different frequencies. Furthermore, the converters for converting electromagnetic energy into mechanical energy are arranged in the downhole instrument in series in order of decreasing resonant frequency, and the dimensions of each of the converters are determined by the magnitude of the resonant frequency, each of which differs from the previous one by an integer of octaves. Furthermore, the cable which connects the generator of electromagnetic pulses to the downhole instrument is coaxial with a wave impedance which is equal to the output impedance of the generator and the input impedance of the downhole instrument. | 08-06-2015 |
