Features of the structure and identification the complex reservoirs of Kashirskian-Podolskian deposits on an example of one of the fields of Bashkortostan

The structure of complex Kashirskian-Podolskian carbonate reservoirs of Bashkortostan is considered. The sediments are a complex deposit system representedby alternation of dense carbonate lithological varieties, productive reservoirs and nonproductive microgranular chalky pelitomorphic rocks, which can contain both bound and free water. Irrational alternation of listed above lithological varieties cause difficulties in log data interpretation. The features of reservoir identification and estimation of fluid content in Kashirskian-Podolskian deposits are represented.
Materials and methods
The modified technique of reservoir and lithological identification in Kashirskian-Podolskian deposits.
Results
The features of the structure of Kashirskian-Podolskian deposits are presented. The technique of reservoir and lithology identification is modified.
Сonclusions
At irregular alternation in the section of productive reservoir rocks and pelitomorphic intervals the problem of lithologic identification is particularly pointed. The confident technique of reservoir identification and separation from pelitomorphic intervals is suggested.
