| 摘 要： | 鄂尔多斯盆地中奥陶统马家沟组由于受加里东运动影响而隆起抬升遭受风化,形成良好的岩溶油气储层。因此,对马五段上部马五1～4亚段的沉积微相研究对未来在该层位的油气勘探具有深远的意义。本文运用单因素分析多因素综合作图法结合钻井岩心资料、测井资料的细致分析、统计,选取了白云岩含量、灰岩含量、膏盐含量及泥岩含量等单因素,绘制出马五1～4各地层的沉积微相图。研究表明马五期的沉积格局为局限台地,自西北向东南依次出现台内斜坡、台内浅凹、台内盆缘,其沉积演化从马五4的低海平面期到马五3的海平面上升期再到马五2的顶盛期最后到马五1的海退期,形成一个完整的海进海退沉积旋回,并依据其沉积特征建立了各时期的沉积模式。

| Abstract: | The Majiagou formation,Middle Ordovician,in the Ordos Basin had become a nice karst reservoir since it was uplifted in the Caledonian movement and eroded.An elaborative study of micro-sedimentary facies is of great significance in the oil-gas exploration.The micro-sedimentary face maps of Ma5 1-4 submembers were compiled from statistics data of drilling cores and logging and detailed analyses of data obtained by single factor analyses(including contents of dolomite,limestone,gypsum and mudstone) and multifa... |
