DEVELOPMENTS IN THE FLUID DYNAMICS AND HYDROCARBON MIGRATION OF SEDIMENTARY BASINS

Fluid dynamics is the nucleus of basin fluid geology.The analysis on the development characteristics and evolutionary history of fluid dynamics is an effective way to study hydrocarbon migration and accumulation at present.Because of the violent deformation of Chinese sedimentary basins in the later stage,hydrocarbon as a fluid mineral,the dynamic feature of its migration,accumulation and occurrence location becomes even more evident.To recognize and evaluate the influence of deformation on basin fluid dynamics will be helpful to the more scientific and effective research of hydrocarbon migration.Based on the comprehensive analysis of function mechanism of the factors affecting basin fluid dynamics,including the burial and diagenesis of sediments,the infiltration of meteorological and surface water,tectogenesis and the relative distribution of underground fluids,the development and difficulties of basin fluid dynamics research at present were expounded,the evolutionary characteristics of basin fluid dynamics were summarized,and some key scientific problems remaining to be solved in the furture research were put forward so as to make further progress in the domain of this research.
