摘要
油气勘探应从"区域评价突破"和"典型解剖"两方面着手。扬子北部大陆边缘(中扬子区)、前陆盆地与逆冲推覆构造带(苏皖南部、南盘江地区)应是近期勘探目标;圈定古隆起及区域性间断面是勘探决策的关键;裂缝和裂隙发育带在富集成藏中起重要作用,然而区域性封闭(包括压性断面)对保存油气藏更为重要。提出了今后五年油气勘探的区域范围。
The oil and gas exploration should be put on with the breakthrough of regional evaluation and the dissection of tvpical cases in southern China.The exploration tareets in the near future could be the continental margin in nortnern part of Yangzi region-the tnrust nappe zones in nanpanyang area,the foreland basins in southern part of Jiangsu-Anhui.The key step is to identify paleouplifts and regional dis- continuity surfaces.Fractures and fissure-developing belts play important roles in hydrocarbon accumula- tion,but more important are the regional closures to preserving hydrocarbon.Possible potential blocks and zones for the exploration in the next five years have been suggested here.
