METHOD AND APPARATUS FOR COMPLEX ACTION FOR EXTRACTING HEAVY CRUDE OIL AND BITUMENS USING WAVE TECHNOLOGIES

摘要

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. The use of the invention makes it possible to increase the efficiency and environmental friendliness of extraction of high-viscosity, heavy oil or bitumen from a horizontal well due to the complex application of acoustic and electromagnetic wave technologies.
