渤海盆地石油成因的探讨

摘要:

本文提出了渤海盆地的石油成因。其形成过程是,地台强烈地活化,形成大量断陷盆地,使被深埋的沉积物处于高温状态,下部温度高,炭同水反应产生一氧化碳和氢气,上部温度稍低,有机质热解产生烃类,以及一部分来自岩浆活动中的一氧化碳和氢气,这些油和气沿断裂上升,被盖层阻挡浓集,之后在漫长的地质过程中合成了石油。

STUDY OF THE PETROLEUM GENESIS IN BOHAI BASIN

Abstract:

The petroleum of Bohai Basin is formed by strong activation of the platform which is similar to tectogenetic margin in struture. The activation of platform forms numerous fracture basins, which possess some deep fractural charcteristics and connect the earth crust at great depth, therefore the basin has enough thermal energy there carbon and water in the sediment buried under high temperature condition would to produce carbon monoxide and hydrogen, thermal decomposition of organic matter produce hydrocarbon as well as carbon monoxide and hydrogen from magma, then these gass rise up along fracture zones within this basin. Upon being blocked by the cap of sediments, they would concentrate there under presure and be synthesized into petroleum in the long geological years.

Key words: Bohai Basin Petroleum genesis
