摘要
通过对辽河盆地桃园构造地震剖面的分析对比，总结出老第三系东营组地层的地震相特征，并建立了地震相与沉积相的对应关系，划分了东营组地层的地震沉积相带，得出该构造东营组地层属河流泛滥平原沉积体系。据５口产气井所钻遇的储层岩性及所处相带分析，该构造有利的储层为砂质漫滩砂体，有利于储集天然气的相带为河流砂质漫滩微相带。
The characters of the seismic factes of the Eogene Dongying Group in Taoyuan structure are summarized by analyzing and contrasting the seismic sections. The corresponding relations within seismic factes and sedimentary factes are set up. The seismic sedimentary factes beltsare divided. It is concluded that Taoyuan structure belongs to a river and flood plain depositionalsystem , the favourable reservoir is a sandy flood land and the favourable factes belt is a river sandyflood land microfacies belt by analyzing the characters of reservoirs in 5 producing gas wells andtheir locations.
