摘要
鄂尔多斯盆地东部下奥陶统储层含油气差异性的关键是储层储集条件的非均一性，根本原因是基底构造古隆起及凹陷、岩相古地理、成合作用和占岩溶的综合影响．其中，基底构造古隆起及凹陷是基础，岩相是条件，成岩作用是关键，古岩溶是决定性因素。
The petroliferous diffence of the Lower Ordovician reservoir rocks in the eastern Or-dos Basin is resuIted from the non-uniformly geological conditions for the reservoir rocks,which is an interaction of paleo- elevation of the basement structure,and depression,lith-facies and paleogeography,diageneLsis and paleokarstification,among those factors,paleo-elevation of the basement and depression are the foundation,lithfacies is the geological condition,diagenesi is the key to geological process, and paleokarstification is a decisive factor.
