| Abstract: | The software package of the Monte Carlo method to simulate neutron logging is developed, which can be used for the computation of the neutron flux distributions with the space, energy and time. Under the conditions of a open hole well without instrument in the borehole, with fresh water saturated limestone formation and injected fresh water in borehole, the software package is used to compute the various porosity neutron flux distributions with the energy and time for the certain points along borehole axis and wall, and the time spectra of thermal neutron, the time spectra of epithermal neutron. It has also been studied that the variation of porosity influence on neutron flux distributions with the energy and time, the time spectra of thermal neutron and the time spectra of epithermal neutron along the borehole axis and wall. |
