葡北油田是大庆长垣开发较为成熟的区块,开发实践表明,在现阶段密井网条件下,断层边部剩余油仍较为富集。为达到精细挖掘断层边部剩余油的目的,传统的断层解释方法已无法满足现阶段油藏精细描述的需求。因此,需采用人工地震解释成果作为约束,结合三维可视技术,初步刻画断层大体产状。然后利用等时切片、纵向时窗加密和制作等时属性切片的方法进行断层的精细刻画。结果表明,该方法取得了良好的应用效果。

Pubei oilfield is a mature block in Daqing Changyuan development and the practice shows that the remaining oil in fault edge is still relatively enriched under the condition of dense well pattern.For the purpose of excavating elaborately the remaining oil at fault edge,the traditional method of fault interpretation cannot meet the needs of detailed description of reservoir at the present stage.Therefore,the interpretation result of artificial earthquake is needed as constraints to describe the general occurrence of fault with the combination of 3 Dvisualization technology.Then,the fine description of fault is performed by means of isochronous slice,longitudinal time window encryption and the method of makingequational attribute slices.It turns out that this method has a good application.
