摘要： Methods and related systems are described for the detection of nuclear radiation. The system can include a tool body adapted to be deployed in a wellbore and a scintillator material that intrinsically generates radiation. The scintillator material is mounted within the tool body. A photodetection system is coupled to the scintillator material, and mounted within the tool body. Features in a spectrum associated with a scintillation material's intrinsic radioactive decay are used for the determination of one or more parameter's of the response function of the radiation detector system.

摘要： Methods and related systems are described for the detection of nuclear radiation. The system can include a scintillator material that intrinsically generates radiation and a photodetection system coupled to the scintillator material and adapted to generate electrical signals based on light emitted from the scintillator material.

摘要： Systems, methods, and devices for thermally protecting a scintillator crystal of a scintillation detector are provided. In one example, a thermally-protected scintillator may include a scintillator crystal and a thermal protection element, which may partially surround the scintillator crystal. The thermal protection element may be configured to prevent the scintillator crystal from experiencing a rate of change in temperature sufficient to cause cracking or non-uniform light output, or a combination thereof.

摘要： A method for a pulsed gamma-gamma density tool to simultaneously compensate for interactions due to the photoelectric effect and density variations caused by standoff enables a more precise determination of bulk formation density. This method includes the steps of providing a source of energetic particles and directing those energetic particles at a formation having a known photoelectric factor and electron density and capturing one or more photons either emitted or deflected from the formation either a first detector or a second detector. The first detector is spaced a first distance from the source, the second detector is spaced a second distance from the detector and a third distance separates the first detector from the second detector. Measuring a first total energy of the photons striking the first detector during a time interval and measuring a second total energy of the photons striking the second detector as a function of the time interval and disposing a first filter between the first detector and the formation effective to cause Pe response to match standoff influence thereby compensating for both effects simultaneously. In addition to the first filter, the required compensation may include a second filter between the second detector and the formation as well as adjustments to the respective first distance, second distance and third distance.

摘要： A more precise determination of bulk formation density is attainable using a pulsed γ-γ density tool and simultaneously compensating for interactions due to photoelectric effect and density variations caused by standoff. A source directs energetic particles at a formation having a known photoelectric factor and electron density. One or more photons either emitted or deflected from the formation are captured at a first or second detector, respectively spaced at first and second distances from the source, and separated from each other by a third distance. First and second total energies of the photons respectively striking the first and second detectors are measured during a time interval. A first filter is disposed between the first detector and formation effective to cause Pe response to match standoff influence, thereby compensating for both effects simultaneously. In some embodiments, a second filter is provided between the second detector and formation.
