研究并讨论地层切片技术在复杂断陷盆地岩相识别中的应用及对策,以准确反映盆地中沉积体系的展布,精细刻画振幅型和结构异常型沉积体系.应用地层切片技术,结合三维精细解释结果及三维可视化方法,在海拉尔盆地贝西次凹霍1井区识别了下白垩统大磨拐河组河道的展布并刻画了下白垩统南屯组扇体发育的特征.

The application of stratal slicing in lithofacies identification in a complex fault basin can accurately reflect and finely depict the distribution of depositional systems with amplitudes and abnormal structures in prospecting areas. Combining with results of detailed 3-D interpretation and 3-D visual technology, this stratal slicing technique was successfully used to identify the configuration of the lower Cretaceous Damoguaihe channel sands and develop characteristics of the lower Cretaceous Nantun depositional fan in Well Huo-1 area of northwest Beier Depression, Hialaer Basin.
