| 摘 要： | 以井-震精确标定为基础,借助地质-地球物理建模技术,建立了长兴组生物礁滩体岩性相—测井相—地震相—属性相—储层相(沉积微相)之间精确对应关系。在此基础上,利用地震敏感属性提取及反演方法,精细刻画了礁滩体沉积微相空间展布形态,并结合伽马测井约束的波阻抗孔隙度反演技术对礁滩体储层物性空间分布进行预测。通过与已有钻孔比对,发现储层预测效果不仅与勘探实际相吻合,且具有较高的预测精度。由此认为,地质与地球物理互动反馈的储层预测方法不仅对元坝地区生物礁滩气藏勘探具有理论性指导意义,而且对其他地区礁滩隐蔽油气藏的勘探具有实际性借鉴意义。

| Abstract: | In this paper,based on the well-seismic precise calibration and geological-geophysical modeling technology,the corresponding relationships among the lighologic facies,logging facies,seismic facies,attribute facies and reservoir of Changxing Formation were established.Furthermore,by means of seismic attribute extraction and inversion,the sedimentary macrio-face spatial distribution was described clearly.Meanwhile,combined with impedance inversion technique of the gamma logging,the spatial distribution of ree... |
