Annotation:
Texturally inhomogeneous rocks are characterized by degraded filtration and capacitance properties, complex petrophysical models that often differ from traditional ones, which accordingly affects both the indications of well logging methods and the information content and the reliability of the geological interpretation of well log materials. In accordance with this, the possibilities of identifying texturally inhomogeneous reservoir rocks based on core and well log data were analyzed. The paper considered the possibilities of identifying texturally inhomogeneous reservoir rocks according to micro log, microblock method, lateral logging, gamma-ray logging, gamma-gamma lithodensity logging, neutron-neutron logging, nuclear magnetic tomographic logging, core photographs were used under natural and ultraviovet (UV) illumination. Based on the results of the analysis, the features of the considered modification of the nuclear magnetic tomographic logging (NMTL) in the allocation of reservoirs were shown, the limitations and possibilities of the allocation of reservoirs according to GIS and core data were also considered.
