| 摘 要： | 冀东地区发育有多个潜山,潜山地层由中生界、古生界、元古界及太古界-下元古界结晶基底组成,潜山发育有侏罗系、奥陶系、寒武系和太古界花岗岩四大套储层,以及上第三系明化镇组、上第三系馆陶组、白垩系泥岩、侏罗系煤系地层,寒武系徐庄组、毛庄组、馒头组泥页岩盖层,且储盖组合良好,油气成藏的关键因素是油源,并以南堡凹陷下第三系烃源岩最佳;总结了潜山的新生古储型成藏组合和单侧-它源-侧向-潜山成藏模式,认为南堡凹陷下第三系生成的油气可以通过深大断裂和不整合面运移到潜山有利部位的多个目的层中聚集成藏;潜山油藏的分布规律是沿富油凹陷周边潜山的大断裂和不整合面发育带分布,在油源断层的交汇处附近富集.

| Abstract: | There are several buried hills in Eastern Hebei Province,with the formation of Mesozoic,Palaeozoic,Proterozoic and Archaean Era-Palaeoproterozoic crystalline basement,and four reservoirs of Jurassic system,Ordovician system,Cambrian system and Archaean group.The cap formation includes Minghuazhen Formation,Guantao Formation,Cretaceous shale,Jurassic coal and Xuzhuang,Maozhuang,Mantou formation shale of Cambrian system and the reservoir-cap combination is fine. The key to hydrocarbon formation is oil source and the source rock of Paleogene for Nanpu sag is as major source rock. The combination of new oil source beds and the previous reservoir-like pool formation for buried hills and pool models of single side, other source, lateral and buried hill are summarized. It is considered that the accumulated hydrocarbon of Paleogene for Nanpu sag is moved and immigrated to some target zones of favorable areas by deep and large fractures and unconformabilities. While the buried hill hydrocarbon reservoirs are distributed along the large fractures and developed unconformable zones for circumferential buried hills round sags with rich oil and accumulated over the cross of oil resource faults. |
