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。
The study of fluid potential in the basin is an important part of the basin analysis and also the core of hydrocarbon accumulation kinetics. The study of fluid potential in the basin can clarify the history of basin evolution, indicate the migration direction and accumulation area of oil and gas, and guide the division of hydrocarbon accumulation system. Fluid potential research is mainly through basin modeling, fluid inclusion analysis and seismic velocity analysis. Basin simulation has good visualization, but involves more parameters. Fluid inclusion analysis has high accuracy, but the data is limited, and the calculation is difficult. The seismic velocity method has a wide range of work areas and is suitable for early exploration. Comprehensive use of three methods to correct each other, so that fluid potential evolution of space-time analysis.
