The apparatus for a borehole influx fluid parameters measurement comprises an enclosure open on two adjacent sides and having a poorly deformable heat-insulating rear wall, a cover and side walls made of elastically deformable heat-insulating material. Inside the enclosure a cellular structure of elastically deformable heat-insulating material is mounted with the gap relative to the enclosure's rear wall and having the through cells insulated from one another. Said cells forming the apparatus inlet openings on one side of the cellular structure and on the other side they are connected with the gap, the total area of the inlet openings significantly exceeds the area of the structure side surface they are located at. The transducers for the measurement of the influx fluid parameters are disposed inside the cells.
