【摘要】 盆地流体势研究是盆地分析的重要内容也是油气成藏动力学研究的核心。盆地流体势研究可以明确盆地演化的历史,指明油气的运移方向和聚集区域,并指导油气成藏系统的划分。流体势的研究主要通过盆地模拟、流体包裹体分析和地震层速度分析进行。盆地模拟可视性好,但是涉及参数较多;流体包裹体分析法准确度高,但是数据有限,并且求取较为困难;地震层速度法研究工区范围广,在勘探早期较为适用。综合利用三种方法相互校正,从而有可能进行流体势时空演化分析。更多还原

【Abstract】 Fluid potential of a sedimentary basin is not only important in basin analysis but also key of study of the hydrocarbon hydrodynamics.By the study of fluid potential,the evolutional history of a basin,the hydrocarbon migration and accumulation,and the petroleum system can be understood.At present,there are three main methods for the research of fluid potential,namely,basin modeling,fluid inclusion and seismic velocity analysis.Study of fluid potential with basin modeling is good at the 3D visualization,but the involved parameters are too much.Fluid inclusion analysis is much precise.The seismic velocity analysis is wide in research scope,which especially can be applied in early stage of petroleum exploration.The combination of three methods can make the study of fluid potential be done from point(line) to plan and to 3D,which is the future direction for the study of fluid potential.更多还原
