Title
DEVELOPMENT CHARACTERISTICS OF FLUID DYNAMICS IN REFORMED BASINS
摘要
流体本身的运移性与含油气盆地后期的改造作用,导致了油气流体在地质历史上可具有多期运移、聚集、成藏和破坏的过程。在对准噶尔、鄂尔多斯等盆地进行流体动力学研究的基础上,总结出改造型盆地流体动力学的三个主要的发育特点 :平面上流体动力场往往被分隔成若干个相对独立的流体动力体系;地质历史上流体动力的分布与演化具有阶段性;空间上,不同地层的流体动力分布格局并不完全重合。
Abstract
The migration nature of fluid and post-reformation of petroliferous basins resulted in multi-period of migration,accumulation,pool-forming and destruction of oil and gas in geological history.On the basis of the researches made on fluid dynamics in Junggar and Ordos Basins,three major characteristics of fluid dynamics of reformed basins were summaried:1.plannar fluid dynamic field could usually be divided into several relatively independent systems;2.the distribution and evolution of fluid dynamics could be divided into different stages in geological history;3.the distribution patterns of fluid dynamics of different strata were not always coincided in space.
