摘要
针对准噶尔盆地腹部巨厚沙漠覆盖区特殊的地震地质条件及侏罗系和白垩系岩性油气藏勘探需求,进行了可控震源高密度采集试验,通过采用炮点预设计、可控震源低频设计、可控震源滑动扫描、地震资料快速检查评价等技术,实现了沙漠区可控震源高效高密度三维地震采集,资料品质得到明显改善。试验证明,在准噶尔盆地腹部巨厚沙漠区采用可控震源高密度采集是可行的。
In view of the special seismic geological conditions of thick desert area in hinterland of Junggar basin and the needs of exploration of the Jurassic and Cretaceous lithological reservoirs, high-density vibroseis acquisition test is carried out. Using shot pre-design, vibroseis low frequency design, vibroseis slide scanning and seismic data quick inspection and evaluation technologies, the vibroseis efficient high-density 3D seismic acquisition is performed in this desert area, and available data quality has been significantly improved. The test proves that the high-density vibroseis acquisition is feasible in thick desert area of hinterland of Junggar basin.
