thermal history - Opis:
- A highs ignifance of the Kutno 2 deep borehole is due to its location in the central zone of the Polish Basin where the Rotliegend complex has previously never been achieved by other drill holes and thus was not recognized and studied. Drill core from the Rotligend of the Kutno2 has been recently studied for its petrography and facies. The Rotligend in this zone is represented by fluvial and alluvial sediments. It is composed mainly of fine- to coarse-grained sandstones, with conglomerate inter beds. Diagenetic processes of the sediments have been dominated by mechanical and chemical compaction, as well as by transformation of the unstable mineral components. Fluid inclusion analysis for quartz and carbonates indicates that the diagenesis-associated temperature reached 120-180°C. The presence of haematite pseudomorphoses after framboidal pyrite indicates an extremely high palaeotemperature of approx. 500°C. Itis related here to the Jurassic hydrothermal event. The recent very high reservoir pressure might be associated with high temperatures due to the aqua thermal pressure mechanism.
