| 摘 要： | 通过岩矿特征、剖面结构、砂岩粒度和砂体形态分析，认为埕岛油田馆陶组上段为曲流河沉积。按砂体发育特点和成因类型划分出主河道连片砂体、河道边缘连续窄带状砂体、天然堤断续带状砂体、决口水道扇形席状砂体及废弃河道成因的透镜状砂体等5种类型。在研究区383口井精细地质研究的基础上，从不同成因储油砂体角度总结出夹层分布特征。建立了储油砂体内夹层的空间分布模式：主河道砂体内夹层分布复杂，一般底部发育钙质夹层，中部多发育物性夹层，上部为泥质夹层；河道边缘砂体主要发育泥质夹层；决口扇砂体内泥质夹层分布稳定；天然堤和废弃河道仅发育极少的钙质夹层。

| Abstract: | The analyses of lithology characters,the profile construction,grain size and the sand body morphology reveals that the upper segment of Guantao formation of Chengdao Oilfield belongs to meandering river deposition.According to the sand body feature and the genetic type,sand bodies are divided into five types:sheet pattern sand body of main channel,the continuity narrow banded sand body of channel border,the intermittent banded sand body of natural levee,the fan-shaped sill-like sand body of crevasse channel... |
