Abstract

Abstract: Weathering crust reservoir has special characteristics. Combined with the discovered weathering crust reservoir in the world, the connotation of weathering crust reservoir was defined, three-level classification was made, and its characteristics and global distribution were present. The weathering crust reservoir can be subdivided into two types:uplift weathering crust reservoir and basement weathering crust reservoir. The weathering crust reservoir is distributed to almost all of the oil-gas province in the world and geologic eras. The lithology of the weathering crust reservoir includes clastic rock, carbonate, magmatic rocks, and metamorphic rock. The type of the reservoir space is included in pores or hole, fracture and fractured pores. The weathering crust of different lithology forms different hierarchical structure and reservoir space combination, and large scale distribution. Multiperiod large and medium sized unconformities developed in superimposed basins in China. It leads to wide distribution and great exploration potential of weathering crust reservoir in China. It is main to prospect basement weathering crust in the superimposed rift basins in eastern China, and uplifting weathering crust in the superimposed craton-foreland basins in the middle and western China.

Key words: low permeability reservoirs, diagenesis, physical property evolution, hydrocarbon filling, the third member of Dongying Formation, Bozhong Sag
