摘要： Various embodiments include systems and methods to provide a pulsed chemical neutron source. The pulsed chemical neutron source can be used in well logging applications. Apparatus can be arranged to generate neutrons from a chemical neutron emitter and to pass the neutrons through an aperture of a neutron shield when the chemical neutron emitter aligns with the aperture such that the neutrons are substantially blocked by the neutron shield when the chemical neutron emitter is unaligned with the aperture. In various embodiments, movement of one or more of the chemical neutron emitter or the neutron shield can be controlled such that the aperture and the chemical neutron emitter operatively align with each other during a selected portion of the movement, generating pulses of neutrons output from the neutron shield. Additional apparatus, systems, and methods are disclosed.

摘要： A method and logging tool for evaluating the cement behind casing. In an embodiment, a collimated source emits gamma rays at selectable elevation angles. A fixed collimated detector received reflected gamma rays. Reflected calibration gamma rays are measured in a wellbore section having a cement layer of known condition. Backscattered evaluation gamma rays are measured in a section of wellbore to be analyzed and are compared with the backscattered calibration gamma rays to provide an indication of the quality of the cement layer at that location.
