摘　　要：南阳凹陷地下地质条件复杂,就圈闭而言几乎都以小断块、小断块群面貌出现,面积大多小于1km2,含油带窄,充满系数低。复杂的储藏条件使小断块圈闭钻探风险很高。三维地震一体化解释方法的应用,提高了该类地区的钻井成功率。对复杂断块的解释主要运用了三维地震一体化中的相干体技术、可视化技术、层位空间自动追踪技术等。利用该方法在南阳地区优选的3个小断块圈闭,经钻探试油,均获工业油气流。Nanyang depression has complex subsurface geo-logic conditions and small fault block traps with area s smaller than1km 2 ,narrow oil-bearing zones and low fill factor.Exploratory drilling in small fault block traps is at high risk due to the complex reservoir conditions.The application of integrated3-D seismic interpretation techniques such as coherence cube,visualization and au-tomatic tracing of horizon improved the success rate of exploratory drilling in this area.Drilling in3small fault traps selected with this method in Nanyang depression discovered flow oil and gas.
