| 摘 要： | 冀中坳陷苏桥地区奥陶系储集层的储集空间为古岩溶与构造裂缝构成的裂缝一次生孔隙类型。溶蚀孔隙型储集层主要发育在泥-粉晶白云岩和细-粗晶白云岩中，加里东期古岩溶形成的孔洞基本被充填，但为后期发育埋藏岩溶提供了重要条件；燕山-喜马拉雅期的淡水岩溶主要发育在断层附近的白云岩或裂缝发育的石灰岩中，是奥陶系碳酸盐岩储集层主要储集空问之一。裂缝发育主要有5期，均对储集层物性有建设性意义，储集层发育与裂缝的发育程度呈正相关。图5表1参10 |

| Abstract: | The Ordovician carbonate reservoirs in the Suqiao buried hills zone of Jizhong Depression mainly consist of crack and secondary pore spaces, which are formed by paleo-karst and tectonic splits. Dissolved pores developed in micrite-powder dolomite or fine-sparry dolomite. The fresh water karst during Yanshanian-Himalayan tectonic movement occurred near the fault, which developed in dolomite and cracked limestone, is one of the contributors for the Ordovician' reservoirs. The cracks developed in 5 episodes and they are basement for forming the reservoirs and the reservoir development has a positive relationship with the development of cracks. |
