最近 2 0年来 ,在鄂霍茨克海北部陆架区进行了大量的区域性地质—地球物理研究工作 ,这使我们可以探讨这些新生代沉积盆地的结构 ,预测和评价它们之中一系列有远景的含油气体系。在裂谷生成区内 ,沉积盆地呈雁行状分布 ,并具有总的似菱形或S状形态。盆地沿长轴延伸 2 0 0～ 40 In the recent 20 years, a large number of regional geologic-geophysical studies have been conducted in the northern Okhotsk shelf region, allowing us to explore the structure of these Cenozoic sedimentary basins and to predict and evaluate a series of promising Oil and gas system. Within the rift-forming area, the sedimentary basins are geese distributed in the shape of anagrams or S-shape. The basin extends 200 ~ 40 along the long axis
