地壳现代运动与油气藏储量的回升机理
|
摘要
详细论述了地壳深大断裂及盆地断块构造活动对沉积盖层中流体活动的影响。通过对俄罗斯境内几个大含油气区(高加索、西西伯利亚、鞑靼斯坦)大量实际资料的分析指出,在一些老油气田已开发多年的区块内和一些早已报废的井中,储量和产量的回升现象是普遍存在的,这种现象的出现与深部地壳动力学环境周期性的改变有着密切的关系。
The effects of the deep fractures of crust and block tectonic movements on the fluid migration in sedimentary cap rocks are elaborated. A lot of real data from the large-scale petroliferous provinces in Russia such as Caucasia, West Siberia and Tartar are analyzed. It is indicated that ascending reserves and production rates are universally found in old blocks and abandoned wells in old oil-gas fields that have been developed for many years. It is concluded that the emergences of such phenomena are closely related with the periodical changes of the deep crust dynamic environment.
