Abstract:

The deep Es32+3 submembers consist of a set of coarse detritus fan deltaic deposits which come from NE direction and are characterized by near provenance,short transportation and rapid accumulation.Among 8 lithofacies types,the positive rhythmic sand gravel facies,positive rhythmic gravel bearing sandstone facies and massive sandstone facies are favourable reservoir rocks;within 6 facies assemblages,type Ⅰ and type Ⅱ developed in distributary channel subfacies are favourable for oil and gas accumulation.
