Analysis of carbonatization zones as a diagnostic element of the stages of formation of hydrocarbon deposits

Authors: S.A. Fedoseev, Yu.A. Savchenko (Komsomolskneft NGDU, Surgutneftegas OAO, Surgut, Russian Federation
The genesis of carbonate interlayers in the BS10 layer and the role of these ones in the formation of hydrocarbon deposits are examined in detail. The influence of tectonics on the development of fields and the relationship between fractures and carbonate interlayers are investigated. The analysis of the tectonic factor influence on the deposit formation is executed.
Key words: carbon-bearing prolayers, post-sedimentation genesis, oxidation-reduction conditions, coal acid, dehydration, a biogene carbonate.
