Information × Registration Number 0206U004193, 0101U000285 , R & D reports Title Physical, mathematical and petrophysical models in the direct and inverse multispace problems of neutron logging of oil and gas wells. popup.stage_title Head Kozachok I.A., Tsyfra I.M., Registration Date 14-02-2006 Organization Institute of Geophysics by S.I.Subbotin name (Division of Geodynamics of Explosion). popup.description2 The new (alternative) models of parameter interpretation of multispacing neutron logging data have been proposed. They are directed on the algorithm solution of inverse problems arising on investigations of oil and gas boreholes with the help multispacing neutron logging and other borehole geophysics methods. The method of reduction of mathematical physics differential equations by using the operators of non-point symmetry has been proposed. The efficiency of the group method is illustrated by the examples of neutron diffusion problem in gradient inhomogeneous medium and slowing down of neutrons.
