Critical techniques for sweet spot prediction for tight sandstone reservoirs in the Dongsheng gas field and their application effects
东胜气田新召气区位于伊陕斜坡、伊盟隆起、天环拗陷3个一级构造单元结合部,受古地貌和物源影响,不同河道沉积差异大.主要目的层盒1段发育辫状河沉积体系,储层致密且具有典型的低孔、低渗特征,有效砂岩储层薄且含气非均质性强,地震资料分辨率低,甜点预测难度大.据此针对性开展辫状河致密砂岩储层甜点地震预测关键技术研究.首先基于三维地震相对等时面建立地层格架,采用空间相对分辨率地层切片技术刻画不同期次河道砂体空间展布;然后采用小波变换时频分析技术将地震资料从时…查看全部>>
The Xinzhao gas zone of the Dongsheng gas field resides at the junction of three first-order tectonic units:Yishan slope,Yi-meng uplift,and Tianhuan depression.Due to the influence of paleogeomorphology and provenance,different channel sediments vary sig-nificantly in this zone.The main target layer is the first member of the Shihezi Formation,which hosts a braided river sedimentary sys-tem,with tight reservoirs characterized by typical low porosities and pe…查看全部>>
