摘要

利用涠西探区新采集处理的PSDM地震资料,运用层序地层学、沉积学的理论和方法技术,在地震、钻井成果精细解释的基础上,开展了地震属性、地震谱分解、地震波阻抗反演、砂体空间雕刻技术等地球物理综合解释,在探区海中三维工区识别出了非构造圈闭:流沙港组二段岩性圈闭和涠洲组四段岩性圈闭,并对识别的非构造圈闭进行了储层及含油气性分析。研究成果可为涠西探区的钻探目标评价提供依据。

Abstract

By using PSDM seismic data from Weixi exploration area, guided by sequence stratigraphy and sedimentology theory, non-structural traps have been identified through comprehensive geophysical interpretation by seismic attribute study, seismic spectral decomposition, seismic impedance inversion and sand body description on the basis of fine interpretation results of seismic and logging data. The identified non-structural traps are mainly lithologic traps in Member-2 of Liushagang Formation and Member-4 of Weizhou Formation. In addition, analysis about the reservoir and hydrocarbon bearing conditions in the identified non-structural traps has been carried out. The analyzing results can provide basis for evaluation on the drilling targets in Weixi exploration area.
