【摘要】 近年来,随着石油勘探目标由中浅层向深层的过渡,深层地震资料的品质问题也一直困扰着勘探工作者。以东海盆地为例,具体分析了影响深层资料品质的能量衰减、噪音干扰、地震采集、地质条件等各种影响因素。其中能量衰减和噪音干扰因素是深层资料品质差的本质原因。地震采集因素对地震资料的后续处理和解释效果有着决定作用。从外部环境的角度分析了地质因素对地震资料品质的影响。分析结果表明,在面对不同的研究情况时应找到主要影响因素并总结规律,同时不可忽略其他相关影响因素,从而拓宽了研究思路,避免了面对任何情况下都只强调某一单一影响因素的局限认识。

【Abstract】 Recent years,as petroleum exploration targets transit from middle-shallow layer to deep layer,the problem of deep layer seismic data quality always make explorationists confused.Quantitative analysis primarily of energydecay,interfering noise,seismic acquisition and geological conditions influence factors in Donghai basin is maken.The essential reason of poor deep layer seismic data quality is energydecay and interfering noise.Seismic acquisition is the determinant of subsequent data processing and interpretation.Analysis of geological conditions from the perspective of external environment also is maken.From the analysis results,firstly,the chief factors in the face of different situation should be find.Secondly,the rule and not ignore other factors,as a result should be work out.More good ideas in the face of different petroleum exploration situation can be haven.
