For the Middle Jurassic strata, including of the Yu2 and Yu3 levels, characterized by abnormally high reservoir pressures, a sedimentological model is presented, the ranking of sedimentation conditions by sedimentation cycles with the separation of channel facies is performed. The latter, according to attribute analysis, are traced within the study area and are characterized by improved reservoir properties, abnormally high reservoir pressures and high productivity.
