  • The sandstone reservoir of Dongyin Formation, Oligocene Series in Dalujia area is one of the main produc- tion formation of Linpan Oil Field in the Eastern area of China.Its depositional system including delta, espe- cially the delta front part, and its sandbody genetic type including river -mouth bar, sublacustrine distributary channel, sublacustrine levee, sublacustrine crevasse splay and distal bar, have been identified though compre- hensive analysis on core, logging and well log data, and all these sandbody microfacies have different deposi- tional characteristics, well log facies, porosity and permeability.In addition, these sandbodies have strong in- traformational nonuniformity and not so strong an interstratal one.

Study on Microfacies and Reservoir Characteristics of the Delta-Front Sandbody of the First Submember of the Second member of Dongyin Formation, Oligocene Series in Dalujia Area

Abstract: The sandstone reservoir of Dongyin Formation, Oligocene Series in Dalujia area is one of the main produc- tion formation of Linpan Oil Field in the Eastern area of China.Its depositional system including delta, espe- cially the delta front part, and its sandbody genetic type including river -mouth bar, sublacustrine distributary channel, sublacustrine levee, sublacustrine crevasse splay and distal bar, have been identified though compre- hensive analysis on core, logging and well log data, and all these sandbody microfacies have different deposi- tional characteristics, well log facies, porosity and permeability.In addition, these sandbodies have strong in- traformational nonuniformity and not so strong an interstratal one.
