Abstract: In order to identify the productive and perspective perforation in the deposits with scavenger reserves, one often faces a number of problems that prevent the selection of the most perspective intervals. One can add to these intervals the misinterpretation of geophysical well logging, as a result of drill mud colmatation into the formation or technogenic disturbances in the core of rocks that occur during lifting, sample preparation and analysis by classical petrophysical methods. In this regard, the authors of this article present a method of computer x-ray microtomography in order to develop criteria for the prospects of intervals in deposits with scavenger reserves. The article underlines the prospects of the computer xray microtomography method: 3D modelling, calculation of porosity and clay coefficients, volume fraction of heavy minerals, estimation of pore distribution by size and depth of drilling mud penetration of the core, as well as experimental output with recommendations for the usage of method during experiments before and after any impact. In accordance with the research results, we concluded that the method of computer x-ray microtomography under the study of core material can help in the development of effective criteria in order to identify the promising intervals for perforation in the section of a well with deposits with scavenger reserves of hydrocarbon. One can do this if there is a sufficient test and information sampling in relation to the test results under study.
