Title:
APPARATUS AND METHOD FOR ANALYSIS OF GEOPHYSICAL LOGGING DATA USING GAMMA RAYS
Document Type and Number:
WIPO Patent Application WO/2017/007242
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and a method for analyzing geophysical logging data using gamma rays, so as to predict lithofacies of strata by analyzing geophysical logging data, for lithofacies across a wide area, on the basis of data analyzed using gamma rays. The present invention comprises: a gamma-ray emission unit for emitting gamma rays by the nuclear transition of atomic nuclei; a gamma-ray transmission and reception unit for having the emitted gamma rays penetrate through an object and receiving the gamma rays to be received; and a logging determination unit which receives information about the waveforms and wavelengths of the gamma rays emitted by the gamma-ray emission unit, and information from the gamma-ray transmission and reception unit following the penetration of the gamma rays through the object, and produces geophysical logging data for which the information about the speeds, waveforms and wavelengths of the received gamma rays has been analyzed. Thus, the present invention can analyze geophysical logging data, for lithofacies across a wide area, on the basis of data analyzed using gamma rays, by clustering and patterning the results of the geophysical logging data for only significant strata, and can analyze strata with greater accuracy.
