摘　　要：运用沉积物体积分配原理,通过识别沉积基准面旋回产生的层序界面,将钻井、测井和高分辨率三维地震资料相结合,对鄂尔多斯塔巴庙区块二叠系地层进行了高分辨率层序地层对比分析。在上古生界石炭系-二叠系勘探目的层段(本溪组-上石盒子组)划分出3个中期旋回,19个短期旋回,建立了层序地层格架,追踪了SSC4旋回砂层组的空间展布特征,预测了该层序的隐蔽圈闭。In accordance with the sediment volume distribution principle, the sequence boundary caused by sedimentary basic level of deposition cycle, and combining with drilling, logging and high resolution three seismic data, we do a high resolution sequence stratigraphy analysis on Permian sequence in Ordos Tabamiao block. The paper identified 3 mid term cycle, 19 short term cycles in upper Paleozoic carboniferous system exploration objective interval (Benxi formation to Shihezhi formation), established sequence formation framework, purchased space distribution characteristics of SSC4 cycle sand formation group and predicted the subtle trap in this sequence.
