摘　　要：泌阳凹陷安棚深层系属低孔隙度、低渗透率、复杂岩性、微裂缝发育的岩性圈闭型隐蔽性油气藏 ,录井油气显示级别低 ,在常规测井曲线上油气层的响应特征不明显 ,油气层评价遇到较大困难。通过对测井曲线特征分析并结合核磁共振、成像等测井资料 ,总结出该地区的测井评价方法 。Anpong deep strata in Biyang depression is a subtle reservoir with poor porosity, low permeability, complex lithology, micro-fractures and lithologic traps. It is quite difficult to accurately evaluate it since its oil-gas indication is poor, in particular, oil-gas responses on conventional logs are not clear. On the basis of log characteristic analysis and combination with nuclear magnetic imaging logging data, a log evaluation method available for this depression is summarized, from which desirable results are obtained in new wells' production interpretation and old wells' recheck and fine interpretations.
