APPLICATION OF BROADBAND SEISMIC DATA TO PETROLEUM EXPLORATION IN SAG A OF EAST CHINA SEA BASIN

摘要:
东海盆地A凹陷B构造油气勘探中一直存在着中深层沉积体系展布特征不明确和储层甜点发育规律不清晰等基础地质问题。针对这一问题，运用地震精细解释和地质综合分析的方法，利用重处理的高精度宽频地震资料开展了地震沉积学和全频带信息挖掘研究，结合区域地质认识和已钻井地质分析，认识到B构造C段沉积时期发育了东、中、西3条大型曲流河河道带，在中支和西支河道带中发现了3个典型的频率异常发育区，油气检测技术证实是潜在的含气构造，表明B构造C段发育受河道带控制的构造-岩性气藏，为A凹陷B构造中深层油气勘探提供了地质依据，具有重要的勘探实践意义。
Abstract:There are many difficulties in petroleum exploration on the structure B of Sag A in the East China Sea Basin. Many basic geological problems in the middle and deep parts of the field need to be solved, which include the unclear distribution of the sedimentary systems and reservoir sweetness. Combined regional geological survey together with drilling wells, the study of seismic sedimentology and full-band information analysis were carried out based on the broadband seismic data. The results suggest that there were three large meandering river channel systems in the eastern, central and western parts of the structure B respectively during the depositional period of Member C. Three typical frequency anomalous zones were found in the central and western channel systems and the petroleum detecting technology confirmed that they are potential gas-bearing structures. The research shows that the Member C in structure B is a structural-lithologic reservoir controlled by a large meandering river system.
