The Reservoir Characteristics of the Third Member, Shahejie Formation in Ninghai Oilfield

摘要

The study area is located in the southeast part of the Ninghai Oilfield. The north part of the area is bounded by Chenjiazhuang uplift. During the deposition of the third member of Shahejie Formation, sands were transported from adjacent highlands and delivered to the deep basin by turbidity current through major sublacustrine channels which were cut into the lacustrine slope.
