本文主要根据准东石炭系至侏罗系构造发育史及前人对本区油源的研究资料分析建立了北三台凸起西地1号背斜石炭系成藏模式。西地1号背斜石炭系油藏油气源主要来源于与其石炭系侧向接触的吉木萨尔凹陷二叠系平地泉组和顶部不整合接触的平地泉组烃源岩。运移通道主要为断裂、不整合面、高孔渗带及内部高角度裂缝。
Based on the history of the Quaternary Carboniferous to Jurassic structure and the previous research on the oil source in this area, the paper establishes the anticline Carboniferous hydrocarbon accumulation mode of the Beisansai uplift Xidi No.1. The oil and gas source of the Xidadi anticline Carboniferous reservoir is mainly derived from the Permian Pingdiquan Formation and unconformity contact Pingdiquan Formation source rocks in the Jimsar Sag, which are in lateral contact with the Carboniferous. The main migration channels are faults, unconformities, high-permeability zones and internal high-angle fractures.
