FIELD: petroleum industry.
SUBSTANCE: invention is referred to mining engineering and intended for recovery and improvement of performance of geotechnical wells of various design as well as for water sampling from near-filter areas of the wells. The geotechnical well pneumatic and pulsed stimulation tool consists of compressed gas feed pipeline, compressed gas holding tank and gas supply pipeline, water supply pipeline and gas discharge pipeline downhole. The compressed gas feed pipeline is provided with control valve. The T-connector is installed between gas supply, water supply and gas discharge pipelines. Bottom part of the gas supply pipeline is located lower than the T-connector, bottom end of the water supply pipeline being lowered to the well filter.
EFFECT: improved impact stimulation of geotechnical wells and ensured quality of water sampling from near-filter area.
