FIELD: oil and gas industry.
SUBSTANCE: during implementation of the method a container with open lower end of the pipes of the required volume is tightly connected to bore-hole pump inlet; flexible wear-resistant tube is tightly connected to upper part of container to bore-hole pump receiving zone; container is filled with solvent through flexible wear-resistant tube at closed discharge of flow column on well head. After that, solvent from container is supplied to flow column by means of bore-hole pump at open discharge of flow column. It is allowed to supply the solvent to the container at open discharge of flow column at simultaneous mixing of solvent from container to flow column by means of bore-hole pump on condition that solvent supply velocity to the container will not be lower than bore-hole pump capacity.
EFFECT: increasing cleaning efficiency.
