石油深部起源的研究进展

Advances in research to deep origin of petroleum

宇宙动力因素及地球自转速度变化是引起地球排气作用即深部流体上升的外部原因。从太古代至新生代,深部流体的势能不断下降,石油、天然气是晚近期深部流体上升的产物。深部流体上升产生的流体动力学形成流体动力学构造。其中值得关注的是低密带、环状构造及地貌构造结等,几乎所有的油气田均与此有关。基于这样的认识,涌现出了寻找油气藏的新方法,其中有张量分析法、遥感的光学景观模型、岩石放射性法、形态构造模拟技术等。

Outsp ace dynamics and tranges of the earth speed of autorotation are extrernal factors causing earth outgassing,i.e, updraft of deep fluid, From Archaean to Cenozoic, potential energy of deep fluid has been decreased while oil/gas are produced during updraft of deep fluid. Fluid dynamic structure was formed by fluid dynamics caused by updraft of deep fluid. The low density zone, circular structure and relief structure kont should be payed attention because almost all oil/gas fields are related with them.New methods to find oil/gas poot were proposed based on the idea. These methods include tensor analytical method, remote sensing, landscape model,rock radioactivity and shape structure simulation, technique and so on.
