| 摘 要： | 阿尔金断裂和郯庐断裂是亚洲大陆上规模最大的2条晚中生代以来活动的走滑断裂带,前者可能同步错移并分隔曾经统一的古生代克拉通盆地和侏罗纪箕状断陷的原型盆地,后者中段向北错移了属于扬子板块的苏北-胶东地块,北段佳(木斯)-依(兰)断裂切错了松辽与泛三江-哈巴罗夫斯克盆地,敦(化)-密(山)断裂左行错移了鸡西-七台河盆地和虎林盆地.因此,塔里木西南盆地油气资源的勘探评价应与柴达木盆地对比进行,巴丹吉林、腾格里沙漠掩盖下的阿拉善地块可与北塔里木地块对应,在其侏罗系-白垩系陆相盆地沉积之下可能保存了古生代克拉通沉积,可作为有潜力的油气资源战略选区;南黄海中部隆起带是苏北盆地建湖隆起的东向延伸,其震旦系-三叠系海相碳酸盐岩油气藏为潜在的勘探目标区;郯庐断裂北段的构造复位研究,对拓宽东北地区油气资源潜力区和重新认识松辽盆地形成背景、成盆机制有重大的理论与实践意义. |

| Abstract: | The Altyn Tagh fault and Tanlu fault are two of the largest strike-slip faults in the Asian continent that have been active since the Late Mesozoic. The Altyn Tagh fault probably displaced and separated the Paleozoic cratonic basin and Jurassic hstric down-faulted prototype basin, while the central segment of the Tanlu fault displaced the northern Jiangsu-Jiaodong block of the Yangtze plate and the Jiamusi-Yilan fault and Dunhua-Mishan fault in the northern segment of the Tanlu fault displaced the Songliao and Pan-Sanjiang-Khabarovsk basins and sinistrally displaced the Jixi-Qitaihe and Hulin basins respectively. Therefore, exploration and evaluation of oil and gas resources in the southwestern Tarim basin should be considered to be carried out together with those in the Qaidam basin. The Alxa block covered by the Badain Jaran and Tengger deserts may corresponds with the northern Tarim block, and Paleozoic cratonic sediments might be preserved below the Jurassic-Cretaceous terrestrial sediments of the Alxa block. The desert-covered Jurassic-Cretaceous terrestrial basin and underlying Paleozoic cratonic sediments may be considered as potential strategic areas of oil and gas resources. The central uplift of the southern Yellow Sea is the eastward extension of the Jianhu uplift in the northern Jiangsu basin, in which Sinian-Triassic marine limestone oil-gas accumulations are potential targets of oil and gas exploration. The study of structural reconstruction in the northem segment of the Tanlu fault has great theoretical and practical significance for expanding oil and gas potential areas in Northeast China and re-understanding the background and mechanism of formation of the Songliao basin. |
| Keywords: | Altyn fault Tanlu fault structural reconstruction potential area of oil and gas resources |
