摘要
山东济阳坳陷沉积有巨厚的早古生代地层 ,勘探证实其中蕴藏有丰富的油气资源。如何准确识别古潜山界面并对早古生代地层进行精确划分 ,一直是勘探中的难题。通过大量钻孔的测、录井资料 ,系统总结出了济阳坳陷早古生代地层各组的岩性、电性特征及特征岩性 ,并对三种不同类型古潜山界面的识别方法进行了探讨。
The Lower Paleozoic strata of very great thickness containing abundant oil and gas energy, which is verified by the practice of exploration, are well developed in the Jiyang Sag of Shandong Province. But it is still very difficult to distinguish the interfaces between the buried hills and their overlying strata, and to subdivide the Lower Paleozoic strata correctly, in the course of drilling and exploring. After the study of the features of their lithologic, and electric assemblages and characteristic lithology. A method for distinguishing the interfaces between the three kinds of buried hills and their overlying strata is introduced.
