    摘要： The present disclosure relates to borehole logging methods and apparatuses for estimating formation properties using nuclear radiation, particularly an apparatus and method for estimating amounts of silicon and/or oxygen in the formation. The method may include using nuclear radiation information from at least one nuclear radiation detector to estimate at least one parameter of interest. The method may include separating a gross nuclear radiation count into separate nuclear radiation components. The method may also include reducing an error in the estimated formation properties due to speed variations of a nuclear radiation source that activates the silicon and oxygen in the formation. The apparatus may include at least one nuclear radiation detector. The apparatuses may include an information processing device to perform the methods.

    摘要： Method and apparatus for evaluating an earth formation using a pulsed neutron source comprising of dual beams of oppositely directed hydrogen isotopic ions with timing and focal characteristics of each beam set to accomplish a beam-to-beam focusing interaction to a selected position that extends axially along a sealed tube. This makes it possible to generate pulsed neutrons from a plurality of positions.
