Comprehensive assessment of the efficiency of a mobile pulsation unit based on the results of its field tests

\nVarious methods of cleaning the bottomhole zone of an oil reservoir are considered: chemical, mechanical, thermal, acoustic, wave. The disadvantages and advantages of the practical application of hydropulse technologies are shown. To solve the problem of cleaning the bottomhole zone of an oil reservoir from asphalt-resinous and paraffin deposits, water-oil emulsions, salts, as well as generally increasing the well flow rate, a pilot industrial model of a mobile pulsation unit (MPU) has been developed, which allows for the treatment and repair of wells using pulsation technologies. The work evaluates the effectiveness of pulsation treatment using the MPU experimentally on an injection well of the Urustamak field. The results of pilot industrial tests of the mobile pulsation unit showed a 4.5-fold increase in the actual working potential of the well for injection. It was established that low-frequency pulsation action allows for intensifying the process of cleaning the bottomhole zone of the oil reservoir, in particular increasing the intake capacity by an average of 4 times.\n
