【摘要】 地震波形和振幅等地震相特征与油藏储层物性或流体特征具有一定的相关性,通过研究,确定储层物性特征(孔隙度、厚度等)与地震相属性特征(地震波形、振幅等)之间的相关关系,即储层厚度增大或储层孔隙度增大时,对应的地震反射波能量变弱,振幅值降低。以此相关性特征为依据,对阿曼Daleel油田碳酸盐岩岩性油藏的储层分布进行了预测研究,从三维地震资料沿储层顶面反射层提取对应储层段时窗的均方根振幅值,根据中、低振幅特征划出该油田有利储层的平面分布区域。该方法可以在国内外同类型油气田勘探开发领域推广和深化。更多还原

【Abstract】 Such seismic facies characteristics as seismic amplitude and wave form are related to the reservoir physical properties and fluid features.Based on study,the relationship is identified between reservoir features(porosity and thickness)and seismic facies attributes(seismic amplitude and wave form),as well as a simple,rapid,and effective way is figured out to predict the distribution of carbonate reservoir in Omen Daleel Oilfield,which is proved successful and can be popularized in the exploration and development of similar oil and gas fields both in China and abroad.更多还原
