During the operation and repair of wells in oil and gas fields, underground gas storage facilities, there is usually a decrease in the filtration and capacitance properties of the bottom-hole formation zone (PZP) under the influence of a number of reasons. In order to preserve the productivity of wells, the method of increasing the depression on the reservoir during the selection of hydrocarbons is usually used (which often negatively affects the state of the PZP), as well as various physico - chemical and hydrodynamic methods of influencing the PZP to restore reservoir properties in this zone, this is the reason for the relevance of the chosen topic.
Theoretically and practically, the technology of pulse-wave action (IVV) was studied in practice at the Zapadno-Ostaninsky field.
Thus, to solve the problem of the formation of asphalt-resin-paraffin deposits (ASF), improving filtration in the rocks of the bottom-hole zone of the well, it is necessary to choose the most effective technology correctly, including for increasing oil recovery.
