地壳运动与油气田分布
|
摘要
现今地壳运动活跃的构造域有环太平洋构造系、大洋脊构造系与北大陆构造系,在这些构造系中天然地震活跃,深断裂重新活动。天然地震后地面见油苗,美国油气田多分布在破坏性地震带之间,中国已发现的油气田多与活动断裂相伴分布,发现全球油气田中的多一半分布在环太平洋构造系与北大陆构造系内,说明油气田分布与现今地壳运动存在着内在联系,天然地震是地球深部物质外泄的动力,地球深部可能含有石油和烃类气体。因此,现今地壳运动活跃的活动构造系将是油气勘探的重要靶区。
The tectonic domains with active crustal movement may include circum-Pacific tectonic zone,oceanic ridge tectonic zone and northern continental tectonic zone nowadays,in which there exist active natural earthquakes,re-movement of deep faults.Following a natural earthquake,oil shows could always be found on the surface.This is reason why the oilfields in USA are mostly distributed between ru inous earthquake belts,while the oil fields discovered in China are dominantly associated with active faulting.It is con firmed that more than a half of oil fields in the world is distributed within circum-Pacific and northern continental tectonic zones,indicating that the distribution of oil field has internal re-lations to crustal movements,natural earthquake in a force of exo-drainage of the earth's deep fluid or material that may contain crude oil or hydrocarbon gas.Therefore these active tectonic zones in nowadays active crustal movement will be as important targets for petroleum exploration.
