Distribution Regularity of the Wide-Spread Sandstone of He8 Fomation in Ordos Basin

Abstract:

Based on previous studies, the formation mechanism of large-area distribution of sandstone was studied from the views of source supply, ancient terrain, hydrodynamic property and frequent changes of lake level. Sedimentation simulating experiment revealed that the controlling factors of large-area distribution of sandstone include ancient terrain, lake level, source supply, flow, velocity stream. The ancient terrain slope and shallow lake are important geological background, strong source supply is material basis, intersected multi-water is an important way, high velocity stream is considerable driving force, frequent changes of lake level is important controlling factor.
