Аннотация

In the oils of the studied deposits, we detected EPR signals both from vanadium ions and free radicals
(FR). To determine their concentration, the most intense hyperfine structure (HFS) line was used among the
complexes of tetravalent vanadium and a single line from the FR.
There are no noticeable changes in the density of oil and the content of vanadium (IV) in the studied wells from
the area of the Jurassic deposits of the Kyrykmyltyk field. It means that on the area, vanadium content in oil does not
change, there is a good hydrodynamic communication between production wells, and the Kyrykmyltyk field belongs
to low-vanadium oils.
Uniform distribution of vanadium, is also established on the area of the Aptian, Albian and Cenomanian
horizons of the Kara-Arna deposit and it characterizes the conditioned content of vanadium. Between the producing
wells of each horizon there is observed a good hydrodynamic connection.
