ACOUSTIC BOREHOLE RADIATOR Russian patent published in 2001 - IPC

FIELD: geophysics. SUBSTANCE: invention can find use in high-power audio devices for processing of productive zones of oil, gas and water wells to increase their productivity. Acoustic borehole radiator has active modules in the form of piezopackages with face straps tightened by central studs located along axis of rigid lea-tight cylindrical body filled with electric insulation liquid acoustically permeable in area of intervals between modules as minimum. Faces of adjacent modules are fastened together with the aid of spring members and faces of end modules are linked via spring members to face covers of body. Special form of spring member is proposed and optimum value of its flexibility is recommended. EFFECT: increased efficiency and maintainability of radiator which is especially important under specific conditions of operation of borehole radiator. 2 cl, 2 dwg
