| titleOfInvention | High-temperature-resistant and strong-vibration-resistant scintillator packaging device for logging while drilling |
| abstract | The utility model provides a high temperature resistant, anti-high vibration scintillator packaging hardware for logging while drilling, includes scintillator packaging shell, optical window, scintillator, the play plain noodles of scintillator, scintillator rear end face, scintillator side, optics damping layer, transparent coupling medium, side light reflection layer, first side damping subassembly, second side damping subassembly, scintillator rear end reflection stratum, rigid metal plate, rigid damping device, back lid, inert gas and high temperature brazing filler metal melt-seal interface, be formed with the laser welding seam between back lid and the scintillator packaging shell, the scintillator is alkali metal halide or rare earth halide. The space reserved for thermal expansion of the scintillator and the materials inside the package avoids damage to the scintillator due to high temperature, and inert gas is filled in the gap, so that the influence of oxygen in the air on the reflecting material and the light guide material under the high-temperature condition can be effectively reduced, and the stability of the light output performance of the scintillator is ensured. |
