单家寺油田湖相斜坡扇沉积特征 - Most of this area was shallow - lake , semi - deep lake and deep lake sedimentary environment , except that the area around the well ou44 was a set of steep - slope fan - delta and the dawan area was a set of small - scale fan - delta . there were fan - delta , turbidite - fan , shallow - lake , shore - marsh , semideep - lake and volcano - debris facies . in the area of the well ou39 and ou44 , fan - deltas developed both in the middle and the top strata of the third member of the shahejie formation
研究表明，粗面岩sio _ 2含量较高，流动性小，容易形成巨厚的岩钟或岩锥，对成藏有利，同时其位于构造高部位，由于其大部在水面之上，冷却时间长，易于从容结晶，同时还有大量裂缝作为储集和渗滤的空间，使其成为良好的储层。 - ( 4 ) a veries of depositional system of early cretaceous have been identified firstly : basin floor fan , slope fan , leveed channel , subparallel facies , slump facies , lowstand wedge , tst , hst . combining with seismic reflection and log response , this paper discusses distribution of above facies , microfacies and reservoir characteristics
( 4 )首次确定了下白垩统的各种沉积体系：盆底扇、斜坡扇、有堤水道、亚平行相、滑塌相、低位楔、 tst 、 hst ，结合地震反射和测井响应，讨论了它们的分布，微相和储层特征，对今后勘探开发上作无疑有重要价值。
