摘要

构造活动改变地层的空间形态,同时产生周期性的应力震荡变化。油气作为储存在地层中的流体矿产,在运聚期明显要受到构造活动的影响。以库车坳陷为例,通过地质分析、地震现象观察及现代地震学理论的引用,讨论了构造活动促进流体运移的机理、频率和规模。研究认为,构造运动产生的动态效果和静态效果对于油气运聚都有重要作用,尤其是构造活动期间地震泵作用频繁发生,单次作用影响的范围可以远大于构造本身,这种高频率、高强度的周期性应力变化促进了油气运移和聚集。
An active tectonic movement changes the space shape of stratum and result in periodic stress concussion,which will influence hydrocarbon migration and accumulation as fluid deposit in stratum.Taking Kuqa depression as an example,the geologic analysis and earthquake phenomenon observation are made by means of modern earthquake theory,and the mechanism,frequency and scope of fluid migration promoted by a tectonic movement are discussed in this paper.The study shows that dynamic effect and static effect brought by tectonic movement play an important part in hydrocarbon migration and accumulation.Particularly,the earthquake pumping effects during active tectonic movement allow its single influence scope to outclass that by itself.Hence such high frequency and high intensity of periodic stress changes should promote the migration and accumulation of hydrocarbons in Kuqa depression.
