一、两种不同的认识鄂尔多斯盆地是一个在古生界槽台对立基础上发展起来的以中生界为主体的大型沉积盆地。在盆地北部进行前中生界的油气研究工作,应该分析这个地区一度作为大陆边缘的古生代活动背景,恢复到当时的沉积古地理环境,对它的沉积构造格局进行划分。在认识这个地区古生界发展历史,以及在处理活动带与稳定区之间的结合关系上,经常遇到两种不同的意见。 First, the two different understanding Ordos Basin is a platform developed in the Paleozoic basins on the Mesozoic as the main body of large sedimentary basins. In the study of the pre-Mesozoic oil and gas in the northern part of the basin, we should analyze the Paleozoic background once used as the continental margin to restore the sedimentary paleogeographic environment at that time and divide the sedimentary structure. There are often two different opinions encountered in understanding the history of Paleozoic development in the area and in dealing with the bond between the belt and the stable zone.
