Abstract
Abstract Analysis of the lithology of rocks of the pre-Jurassic complex and changes in the reservoir properties of rocks is one of the most important and difficult tasks for the formation of a petrophysical model for the interpretation of well logging data. Despite the long history of geological and geophysical study of deposits of the pre-Jurassic complex, a number of issues related to the reflection in the geophysical parameters of rocks and characteristics of reservoir properties have been studied insufficiently. This is due to the high variability of the lithological composition, textural and structural heterogeneity of the volcanic-sedimentary strata of the Turin Group. At present, the sediments of the pre-Jurassic complex are being actively studied - a representative core is purposefully selected, which is studied using an SCAL, including special methods, modern precision electrical, radioactive and acoustic studies are included in the complex of geophysical studies. The results of new studies are a good information base for refining the petrophysical model of an extraordinary object of study. The aim of this work was to analyze the lithology and reservoir properties of rocks, as well as to identify and classify the main groups of rocks that are possible reservoirs in the sediments of the pre-Jurassic complex within the Frolovsky and Shaimsky petroliferous regions.
