    摘要: Methods for pre-treating packaging materials of particular composition for use in conjunction with a scintillation crystal are disclosed. The packaging materials may comprise a reflecting material, an elastomer, a reflecting fluorocarbon polymer, a polymer or elastomer loaded with a reflecting inorganic powder (including a reflecting inorganic powder comprising a high reflectance material selected from the group comprising Al2O3, TiO2, BN, MgO, BaSO4 and mixtures thereof), or a highly reflective metal foil selected from the group comprising Ag and Al that is chemically compatible with the scintillator crystal. The scintillator crystal may comprise a crystal selected from the group comprising NaI(Tl), LaBr3:Ce, La—Cl3:Ce, La-halides, and La-mixed halides. The method includes subjecting a scintillator packaging material to a pre-treatment while in package form, said treatment selected from the group consisting of heating to a temperature exceeding a proposed operating temperature of the scintillator package, and placing the packaging material under pressure in a confined space until the packaging material is in final form.

    摘要: Systems, methods, and devices for inelastic gamma-ray logging are provided. In one embodiment, such a method includes emitting neutrons into a subterranean formation from a downhole tool to produce inelastic gamma-rays, detecting a portion of the inelastic gamma-rays that scatter back to the downhole tool to obtain an inelastic gamma-ray signal, and determining a property of the subterranean formation based at least in part on the inelastic gamma-ray signal. The inelastic gamma-ray signal may be substantially free of epithermal and thermal neutron capture background.

    摘要: Disclosed is a radiation logging tool, comprising a tool housing; a compact generator that produces radiation; a power supply coupled to the compact generator; and control circuitry. Embodiments of the compact generator comprise a generator vacuum tube comprising a source generating charged particles, and a target onto which the charged particles are directed; and a high voltage supply comprising a high voltage multiplier ladder located laterally adjacent to the generator vacuum tube. The high voltage supply applies a high voltage between the source and the target to accelerate the charged particles to a predetermined energy level. The compact generator also includes an electrical coupling between an output of the high voltage supply and the target of the generator vacuum tube to accommodate the collocated positions of the generator vacuum tube and the high voltage power supply.

    摘要: A method is for detecting gamma rays using a gamma ray detector, and includes determining a first count of gamma rays having an energy in a first energy interval, using a controller coupled to the gamma ray detector. A second count of gamma rays having an energy in a second energy interval is determined, the second energy interval having a higher energy than the first energy interval, using the controller. A third count of gamma rays having an energy in a third energy interval is determined, the third energy interval having a higher energy than the second energy interval, using the controller. The second count of gamma rays is compensated for noise based upon a ratio of the second count and the third count, using the controller.
