| Abstract: | In the neutron well-logging numerical simulation,the calculation of group constants is akey link in improving the precision of theoretical results,This paper tries to apply the neu-tron themalization model in the nuclear reactor physics to the neutron well-logging numericalsimulation,and a calculating method of the thermal group constants under the neutron well-logging conditions is proposed.An appropriate program HGMIC for thermal neutron spec-trum calculation has been developed,and the influence of the borehole temperature on the re-sponses is studied.The correction chart of borehole temperature is drawn theoretically byusing the proposed method and code. |
