【摘要】 由于火成岩的物性与围岩有显著差异,常常对地震资料品质造成严重影响。以东海盆地某凹陷为例,通过研究火成岩屏蔽机理,提出了具体的解决方法,主要对震源容量、排列长度和枪缆沉放深度等采集参数进行了优选。研究结果表明,该方法显著改善了火成岩发育地区地震资料的品质。更多还原

【Abstract】 Because of the significant physical property difference between igneous and enclosing rocks,it often caused serious influence on the quality of the seismic data.By taking a sag in East China Sea Basin for example and based on the analysis of the shield mechanism of igneous rock,a specific scheme for solving the problem was proposed for selecting the best parameters of seismic source volume,streamer spread length and the depths of source and streamer.The studying result indicates that this method can be used to apparently improve the quality of seismic data in igneous rock developed areas.更多还原
