FIELD: foam generators used at drilling wells while carrying out geological exploration works and engineering-geological surveying.
SUBSTANCE: foam generator includes housing where foaming member is arranged, ducts for supplying fluid and discharging foam. Housing of foam generator is secured to drilling column just over rock destructing tool. Foaming member is in the form of hollow cylinder of woven synthetic fibers with fiber weaving density increased from inner surface of said cylinder to its outlet surface. Water mechanically cleaning filter may be used as foaming member, possibly in the form of cartridge SL10 for mechanically cleaning water.
EFFECT: simplified design, improved operational characteristics of foam generator, lowered expenses for drilling wells.
