摘要
鄂尔多斯盆地在奥陶系顶部发育大面积的风化壳岩溶储层。不整合面、溶蚀孔洞缝、岩溶地貌是其区别于其它储层的特殊标志。复杂多变的溶蚀孔、洞、缝及其组合,构成了风化壳岩溶储层的储集空间。该类储层受岩性、沉积相带、古地貌形态、成岩作用改造等因素控制。
There developed a vast area of weathering crust karst reservoirs on top Ordovician in Ordos Basin. Unconformity surface, karst cave and karst landform are signs distinguishing from other reservoirs. The complex association of karst cave and fissures constitutes the reservoir space of weathering crust karst reservoirs. Such reservoirs subjected to lithology, sedimentary facies belt, palaeogeomorphology, and diagenesis.
