| 摘 要： | 在对苏北盆地历年所实施的三维区块进行地震资料评估的基础上,优选了汉留断裂带的永安区块、南部断阶带的竹墩区块进行高精度三维地震采集。从分析苏北盆地地震勘探难点问题着手,应用基于叠前成像的观测系统设计技术、精细的表层调查技术、逐点设计井深和采用小组合基距等六项技术以及严格质量控制体系和措施,通过针对性技术攻关,高精度三维勘探资料品质取得了大幅度提高。通过对永安高精度三维退化方案处理分析,提出了针对苏北盆地不同勘探目标新一轮地震勘探的思路与对策。

| Abstract: | Based on evaluation of 3D seismic data of Subei basin,two blocks,which are Yong＇ an block in Hanliu fault zone and Zhudun block in South fault zone, were selected for high - precision 3D seismic data acquisition. By application of the 6 techniques, such as the pre - stack imaging - based seismic acquisition geometry , fine surface survey, point - by - point depth design , small array base distance, etc. , as well as the strict quality control system and measures, the quality of high -precision 3D exploration data was improved substantially. According to the analysis of high - precision 3D seismic data acquisition method in Yong~n block,it is suggested to employ a new set of seismic exploration strategy and countermeasures for different exploration targets in Subie Basin. |
