摘要
Taking the Qijia buried hill in Liaohe Depression as an example,the electric property and distribution characteristics of interior barriers in the metamorphic buried hills are analyzed,and the controlling effects of the interior barriers on hydrocarbon are comprehensively studied.The results show that the lithology of the interior barriers is mainly composed of lamprophyre and plagioclase amphibolite.The multi-tier distributed interior barriers divides the buried hill into numerous pressure systems,serving as important part of the traps in it.Also,the interior barriers separated oil layers,water layers and dry layers into various hydrocarbon-water distribution models.
