摘要: 对高尘头地区东营组的整个细分对比工作中.垂向上由准层序组到准层序再到小层进行逐级控制,建立井间对比模式,最后由骨架剖面展开,对全区进行细分对比,将东营组划分为3个准层序组,其中合油气主力层东一段戈分为7个砂层组,除第7砂层组外,其余均有油气发现,为该地区勘探开发提供了科学性的指导。

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
