FIELD: purification.
SUBSTANCE: invention relates to technologies of hydrodynamic purification of surfaces of equipment, parts, intervals in perforation of wells from natural and technogenic contaminations. A device for hydrodynamic purification is proposed, containing a flow channel with a profile formed by sections coaxially located and sequentially mated with each other: a cylindrical section, a spherical section, an acute edge section, and a conically diverging section with a conicity angle of 13-14°. A method for hydrodynamic purification of surfaces of equipment, parts, and intervals in perforation in a well is also proposed, consisting in impact on the purified surface with a jet of liquid under pressure flowing in a liquid or gas medium from the device for hydrodynamic purification.
EFFECT: increase in a speed of removal of depositions from surfaces of equipment, parts, while saving a purified surface undamaged and undeformed, as well as from an interval in perforation of wells under high counter-pressure.
