摘要: 通过对准噶尔盆地西北缘山前克拉玛依和乌尔禾地区沉积记录的分析,结合前人在本区的地球物理场、卫星影像和重磁等方面的研究资料,论证了北西向横断裂普遍存在的事实,并从地震剖面上识别出了这些断距较小且具有走滑性质的断层.它们与北东向纵断裂一起形成了本区"纵横交叉"的构造格局.横断裂沟通油源,引导油气侧向运移;纵断裂连接不同时代输导层和不整合,进行垂向调整和分配,从而构成了一个复杂的油气运聚体系.纵、横断裂交汇之处是油气运聚的优势部位,是油气勘探的重点靶区.

Abstract: The NW-trending transverse faults existing in the northwestern margin of Junggar Basin were proved by the analysis of the sedimentary record around Karamay and Wuerhe combined with previous studies on geophysical,satellite-mapping and graviey-magnetic features of this area.The NW-trending transverse faults together with the NE-trending thrust faults constituted the "crossover" structural framework in the studied area.Hydrocarbon migration and accumulation patterns in the area are complex.The transverse faults penetrated into the source centre.Oil and gas migrated along the transverse faults were later vertically adjusted and allocated by thrust faults,high-permeability reservoir rock and unconformity surfaces.The crossover of the transverse and thrust faults is favorable for hydrocarbon migration and accumulation and will become the target for oil and gas exploration.

Key words: northwestern margin of Junggar Basin, transverse fault, sedimentary record, foreland basin, hydrocarbon accumulation
