Patent number: 11346196Abstract: The invention relates to the field of oil production, in particular, to a method for extracting high-viscosity, heavy oil or bitumen. The equipment package includes a ground frequency generator combined with a power and control unit and 2 downhole instruments. One downhole device is an electrohydraulic downhole device with a plasma discharger (hereinafter referred to as DEHDPD) of directional action, designed to create microcracks in the oil reservoir. The second well device has a long length (up to 50 meters) and consists of alternately alternating microwave and acoustic emitters (hereinafter DDMWAE), which simultaneously or alternately affect the oil reservoir. Downhole devices are lowered into the well, their movement along the horizontal well and power supply to them is carried out using a umbilical cable. Oil production from the well is carried out using a pump fixed between the umbilical cable and the DDMWAE.Type: GrantFiled: October 4, 2018Date of Patent: May 31, 2022Assignee: ILMASONIC-SCIENCE LIMITED LIABILITY COMPANYInventors: Alexander Alexeevich Saltykov, Yuriy Alexeevich Saltykov, Anatoly Antonovich Olshevskiy

Patent number: 10987707Abstract: The group of inventions relates to the oil-and-gas extraction industry, in particular to equipment for removing deposits of asphaltenes, resins, paraffins, hydrates, calcium salts, etc. from tubing strings of oil and gas wells without extracting said tubing strings from the wells. This instrument can also be used for cleaning water-extracting wells and other wells. The internal surface of a tubing string is cleaned by a combined action (ultrasonic, mechanical, heat) on contaminants. Owing to the fact that operation of a well does not stop, dirt atomized by the combined action is raised to the surface and removed from the well by a stream of fluid. A system for ultrasonic cleaning of a tubing string consists of an ultrasonic generator and a downhole ultrasonic scraper, which comprises a converter converting electrical vibrations into mechanical vibrations, which is placed into a protective casing and is connected to a vibration transformer, which boosts the amplitude of vibrations of ultrasonic transducers.Type: GrantFiled: November 15, 2017Date of Patent: April 27, 2021Assignee: ILMASONIC-SCIENCE LIMITED LIABILITY COMPANYInventors: Alexandr Alexeevich Saltykov, Yuriy Alexeevich Saltykov, Andrey Alexandrovich Rukhman

Patent number: 10669796Abstract: The method for stimulation of oil production involves the positioning of a downhole device at the operational depth of a well, the device being connected to a surface supply, and the excitation of elastic oscillations of certain distinct frequencies. Furthermore, bottom-hole clogging products are crushed and formation oil recovery is stimulated by a periodic impact on the bottom-hole zone of an ultrasound-range elastic oscillation field in a continuous mode and in a low-frequency pulse mode with simultaneous removal of clogging materials from the bottom-hole oil formation zone. In the continuous mode, the impact is carried out using a high-frequency oscillation of 16-25 kHz, and in the pulse mode, the impact is carried out at a frequency of 1-50 Hz. In terms of their design, the devices for stimulation of oil production consist of the following principal items of equipment: an ultrasound generator, a downhole ultrasonic emitter, a jet pump and a geophysical cable.Type: GrantFiled: August 18, 2017Date of Patent: June 2, 2020Assignee: ILMASONIC-SCIENCE LIMITED LIABILITY COMPANYInventors: Alexandr Alexeevich Saltykov, Yuriy Alexeevich Saltykov

Patent number: 10655412Abstract: An equipment for stimulating increased oil recovery is described. The complex is most suitable for operations in wells where natural flow and gas-lift recovery methods are used, and also for combined treatment of bottom-hole formation zones together with acoustic (ultrasonic) emitters. The complex consists of two main parts: a surface power supply and control unit, and a downhole electro-hydraulic instrument consisting of a boosting inverter unit a capacitor unit and a plasma discharger. Said instrument has a diameter less than 52 mm, allowing the instrument to pass freely through all existing production tubing. The instrument has a modular structure, making it possible to build up the power of the plasma discharge from 0.5 to 3 kJ.Type: GrantFiled: August 18, 2017Date of Patent: May 19, 2020Assignee: ILMASONIC-SCIENCE LIMITED LIABILITY COMPANYInventors: Alexandr Alexeevich Saltykov, Yuriy Alexeevich Saltykov, Vladimir Renovich Genrikhson

Publication number: 20190383124Abstract: The group of inventions relates to the oil and gas production industry, and more particularly to cleaning the near-wellbore region of a horizontal well and also existing filters, as well as to stimulating oil production. The present method includes lowering a complex device consisting of an electrohydraulic emitter with a plasma discharger, a geophysical unit, and an acoustic emitter into a horizontal wellbore as far as the end of the horizontal section, using the geophysical unit to calibrate the instruments and measure the parameters of the wellbore prior to treatment, carrying out acoustic cleaning of the pores of the formation and the filters in the horizontal wellbore region, carrying out plasma treatment of the cleaned region to activate stagnant zones of the formation, measuring the current parameters using the geophysical unit, and repeating these processes throughout the entire horizontal section of the wellbore.Type: ApplicationFiled: November 15, 2017Publication date: December 19, 2019Applicant: ILMASONIC-SCIENCE LIMITED LIABILITY COMPANYInventors: Alexandr Alexeevich SALTYKOV, Yuriy Alexeevich SALTYKOV

Publication number: 20190271202Abstract: The invention relates generally to the field of oil production. More specifically, the present invention relates to the method of oil production stimulation and enhancing oil recovery. The present method is mostly applicable for old oil fields with a low reservoir pressure, marginal wells and heavily clogged wells. The method of achieving the technical result is based on clogging materials crush and their removal from the bottom-hole oil formation zone and its stimulation of oil recovery by means of recurring impact on the bottom-hole zone by an oscillatory field of elastic vibrations within the ultrasonic range and by low-frequency pulse acoustic impact with simultaneous creation of rarefaction space in the perforation zone of the well. The equipment for stimulation of oil production is structurally represented by three basic devices: an ultrasonic generator, a downhole acoustic device and a jet pump.Type: ApplicationFiled: August 18, 2017Publication date: September 5, 2019Applicant: ILMASONIC-SCIENCE LIMITED LIABILITY COMPANYInventors: Alexandr Alexeevich SALTYKOV, Yuriy Alexeevich SALTYKOV
