Origin of super-low permeability sand bodies of Chang 6 oil reservoir set in Huaqing area, Ordos Basin

The theory of sandy debris flowis partial negation and improvement of deep-water sediments concepts such as Bouma sequence and turbidite fan. Based on crop, core observation, sample analysis, combined with sand body characteristics, it is considered that the sandy debris flow is the dominant sediments of Chang 6 oil reservoir set in Huaqing area, which changes the traditional concept of that there is only small-scale turbidite in the center of the lake basin. The further study suggested that the sandy debris flow is mainly controlled by deep water sedimentation slope break belt. The thick-bedded super-lowpermeability sand bodies of Chang 6 oil reservoir set in Huaqing area is typical gentle slope sandy debris flowsediment.
