阳信洼陷火成岩分布与油气关系

阳信洼陷火成岩十分发育,火成岩作用与油气成藏关系十分密切.文章在分析火成岩的地质、地震特征的基础上,描述了火成岩的时空分布,指出由于火成岩发育影响了该区烃源岩的分布,并提高了地温场,改变了烃源岩的地球化学场.火成岩对油气成藏的影响表现在火成岩可以作为较好的储层,火山作用形成了与火成岩有关的复式油气藏,将是下步的勘探方向之一.

Volcanics Distribution and Hydrocarbon Relationship in Yangxin Subsag

There are a lot of volcanics!in Yangxin Subsag.There is consanguineous connection between the volcanics and the petroleum.This paper analyzed the geology and seismic characteristics of the volcanics,and describe the volcanics distribution in the period when it occurred.Volcanics development affected the distributing of the source rock,it also elevated the geothermal gradient,and changed the geochemical field of the source rock.The volcanics may be good reservoir bed,and it can form some multi-hydrocarbon reservoirs,which is one of the prospect targets in Yangxin Subsag.
