FIELD: oil producing industry, particularly, auxiliary equipment for performance of various downhole operations, such as well completion, swabbing, measurements, oil recovery, etc. SUBSTANCE: nozzle has a body with longitudinal hole, thread in upper part and inlet cone in lower part. The body external surface has a variable diameter with a projection formed by upper and lower cones, and hollow formed by middle and lower cones. The projection diameter does not exceed diameter of the lower cone. At level of middle cone, the body has through holes at angles to longitudinal and transverse axes of the body for twisting and intake of fluid into longitudinal hole of the nozzle. EFFECT: increased depression on formation and consequent inflow of oil to well. 3 dwg
