【 摘 要 】

The research area includes Upper Jurassic deposits of Vasyugan horizon. To identify the territorial relationship between Vasyugan and Naunak suites, rugged topography and well profile figurecorrelation have been made; detailed core lithology analysis (Gurarinskaya, Sobolinaya and Yasnaya areas) has been carried out, conclusions on paleoenvironment have been made. It has been identified that sedimentation occurred in the range of the studied territory where continental facies played a more significant role than it was for Vasyugan suite deposits. Thus, the conjunction zone of Ust-Tym depression and Parabel megaswell are spatially the transition zone of lithologo-facial Vasyugan suite replacement into Naunak one.
