GAMMA DETECTOR PROTECTION FOR DOWNHOLE OPERATIONS |
摘要 |
An apparatus and method for protecting sensitive electronics in a gamma radiation detector tool configured to be disposed in a borehole. The apparatus comprises a scintillator crystal and a photomultiplier tube disposed in either a single or individual housings. The housing(s) are bordered by springs configured to dampen axial vibrations. The housing(s) may be dampened from lateral vibrations by a lateral shock reducer on a sleeve that circumscribes the housing(s). The method comprises dampening axial and lateral vibrations to the crystal/photomultiplier during a drilling operation. |
