前言我国东部在大兴安岭、太行山、武陵山一线以东,普遍分布着许多大小不等的中、新生界沉积盆地约40多个。最大的如渤海湾盆地、松辽盆地面积达20～26万平方公里。小的如泌阳凹陷面积1000平方公里。众所周知,这些沉积盆地对我国近期石油工业的发展作出了很大的贡献,已成为我国重要的石油工业基地。随着石油勘探工作的逐步深入,不少单位和同志对这些盆地的形成、发展及其成油规律提出了许多精辟的见解。例如,根据这些盆地的形成和发展分为“断陷”与“坳
Preface In the east of our country, there are about 40 sedimentary basins in the Meso-Cenozoic of different sizes in Daxinganling, Taihang Mountains and Wuling Mountains. The largest such as Bohai Bay Basin, Songliao Basin area of 20 to 260,000 square kilometers. Small as Biyang depression area of 1000 square kilometers. As we all know, these sedimentary basins have made great contributions to the recent development of China’s oil industry and have become an important oil industry base in China. With the deepening of oil exploration, many units and comrades have put forward many brilliant insights on the formation, development and oil formation of these basins. For example, according to the formation and development of these basins, they are divided into “fault depression” and “depression.”
