依据地震沉积学的理论与方法，针对准噶尔盆地东部阜东斜坡区侏罗系头屯河组河道砂体，综合运 用地震属性分析、相干体分析、频谱分解、三维可视化及全三维数据体解释等技术进行了岩性圈闭识别和 新技术的探索。用单一地震属性对岩性目标的刻画具有较强的多解性。为了减少多解性，提高地震属性 的预测精度，采用了多种地震属性进行联合分析、相互验证，以提高预测精度，降低勘探风险。通过应用多 种地震解释新技术对研究区河道砂体进行识别，从多方面清晰地展示了河道砂体的空间展布特征，识别 出了多个岩性目标。经多年的勘探，在该区发现了阜东2 井、阜东5 井及阜东16 井等头屯河组岩性油 藏，为准噶尔盆地岩性油气藏的勘探提供了新的思路和新的勘探目标类型。

Based on the theory and method of seismic sedimentology, according to the channel sands of Jurassic Toutunhe Formation in Fudong slope area of Junggar Basin, this paper carried out identification of lithologic traps and investigation of new technology by comprehensive use of seismic attributes analysis technology, coherence analysis technology, frequency spectrum decomposition technology, 3D visualization and full 3D cube seismic interpretation technology. Because the characterization of lithologic target by single seismic attribute has stronger multiplicity, so multi-attributes analysis was applied to decrease multiple solutions and increase forecasting precision. By mutual verification of these multi-attributes, forecasting precision was improved and exploration risk was reduced. The channel sands of the study area were identified by using various new seismic interpretation technologies, displaying spacial distribution characteristics of sands clearly from many aspects, and many lithologic objects were identified. Through many years of exploration, lots of lithologic reservoirs were found, such as Fudong 2, Fudong 5 and Fudong 16 reservoir. This study can provide a new thinking and new exploration objects type for lithologic reservoir exploration in Junggar Basin.
