辽河盆地陆上地震精细勘探技术攻关及效果分析

辽河盆地经过四十年的勘探开发,剩余勘探目标变得更加复杂,隐蔽性更强,勘探对象的变化对地震资料品质提出了更高的要求。近两年开展了精细采集地震技术,从前期论证开始,针对具体地质目标建立相应的地质模型,进行精细工程技术设计,开展针对性试验攻关,在定量化质量监控下,形成了一套科学、实用的精细三维地震采集技术,主要包括:精细三维工程设计技术、针对地质目标的综合试验技术、最佳岩性激发技术、大型障碍区特观施工技术、定量化质量监控技术等关键技术。同时开展了精细处理及解释方法攻关工作,取得了明显的勘探效果。

Land seismic fine exploration technology research and effect analysis on Liaohe basin

After four decades of exploration and development in Liaohe Basin, the remaining exploration targets have become more complex, more concealed. The change of exploration object set a higher requirement on seismic data quality. We have carried out the last two years fine seismic acquisition technology, started with the predemonstration, established the appropriate geological model to specific geological targets, carried out fine design and targeted research trials,formed a set of scientific, fine and practical three-dimen-sional seismic acquisition technology under the quantitativequality control, which includs: precise three-dimensional engineering design technology, integrated test technology togeological targets, the best rock excitation techniquue, largescale hazard special concept construction technology,quantitative quality control technology and other key technologies. At the same time, carried out tackling key problems on detailed research and interpretation which has achieved significant exploration results.
