DEVICE FOR LOCKING ACOUSTIC TRANSDUCER IN DOWNHOLE INSTRUMENT

摘要

FIELD: estimation of quality of cementing of oil and gas wells by means of geoacoustic apparatus. SUBSTANCE: stack of gaskets closes gap between wall of container and bearing washer, thus excluding forcing of wedge-shaped sealing ring into clearance and ensuring hydraulic seal at increased hydrostatic pressure. EFFECT: enhanced reliability and stability of characteristics of transducer. 1 dwg
