METHOD OF GAMMA LOGGING Russian patent published in 1996 - IPC

FIELD: geophysics. SUBSTANCE: invention refers to geophysics used for search and prospecting of mineral resources. method is realized with the help of passing probe. It provides for allocation of required volume inside rock mass limited by intersection of narrow solid angles of propagation of primary and singly- recorded scattered gamma radiation formed by collimators and sources of detector. Plane where axes of narrow solid angles of propagation of primary and recorded scattered gamma radiation lie is oriented along direction of stratification of rocks of section of boreholes. EFFECT: increased sensitivity of method with simultaneous enhancement of details of search. 3 dwg
