The yanchang formation is divided , for the first time , into six third - order sequences , each with an average time duration of about 4 . 5 ma . the single sequence is composed of deltaic and lacustrine sandstones , siltstones and mudstones . the subaerial and subaqueous distributary channel and channel - mouth bar sandstone reservoirs are well developed mainly in the lowstand and highland systems tracts 論文在富縣探區首次應用陸相層序地層學的觀點和方法,把延長組劃分為6個三級層序,平均時限4 . 5ma ,各層序由三角洲與湖泊相砂、泥巖沉積組成,主要在低位體系域和高位體系域發育水下(上)分流河道和河口砂壩砂巖儲層

Depending on the above studies , the following conclusions can be obtained : 1 ) chang - 6 oil reservoir set of panguliang is a set of continental clastic sediment composed of lacustrine and deltaic system in which estuarine bar is not well developed 研究結果認為:靖安油田盤古梁油藏長6油層組屬于以水下分流河道為主的具有強烈的進積作用,以水下分流河道為骨架砂體,河口砂壩不很發育的河控型湖泊?三角洲體沉積,主要發育三角洲前緣相。

Through the correlation of fan delta to standard deltaic parasequence model , a well - developed fan - delta succession could fall into two parasequences 扇三角洲相在斷陷湖盆的陡坡一側發育,通過與標準三角洲副層序模式對比,一個完整的扇三角洲序列可以劃分出兩個副層序。
