Layer Correlation and Classification of Dongying Formation in Gaochentou Area, Dagang Oillield

Abstract

Abstract: The detailed corltions of vertical control step by step from quasi-sequence series, quasisequence to substratum in Dongying formation of Caochentou area are made, and the model for well to well eorrelation and matrix profile expanding spread is developed. Three quasi-sequence series are cassified from Dongying formation, of which the major oil-gas bearing zone ( Dong- I section) is divided into seven sand layers with oil and gas discoveries except for No. 7 sand layer. These could be as a powerful guide for petroleum explo ration and development in this area.

Key words: Dagang ollfeld, sequence stratigraphy, stratigraphic correlation, sequence
