【 摘 要 】

Based on structural and lithological grid models, a three-dimensional numerical dynamic model of the Mesozoic-Cenozoic sedimentary cover of the Gydan source kitchen and adjacent territories was built. The thermal history of sediments was reconstructed. A map of effective deep heat flow was compiled. A good agreement was found between the measured and calculated degrees of catagenetic transformation for Upper Jurassic rocks. The possible types of kerogens from the main Jurassic and Cretaceous source rock sequences were justified. The study also provides assessments of the volumes of hydrocarbon generation from the main source rock sequences, timing of formation of regional seals and possible extent of hydrocarbon accumulation in structural traps.
