油气运移研究现状及主要进展

20世纪80年代以前,油气运移的研究主要集中在定性实验、机理认识和有机地球化学中油-源对比方面。之后,油气运移的研究呈多样化发展,主要包括:1)小尺度模型物理模拟-大尺度箱状模型-仿真模拟;2)油气运移流体动力学模拟-油气优势运移数值模拟;3)运移机理研究-系统论研究;4)油气运移流体示踪技术地球化学研究;5)网格模型-逾渗模型研究和应用;6)封存箱-幕式成藏理论与认识。未来油气运移学术领域的主要研究方向包括油气在输导层中运移的优势通道、逾渗模型在盆地尺度的发展和应用、断层启闭性评价方法、油气包裹体及自生矿物标志特征和采用动态、定量的动力学方法研究古流体运移问题的三场耦合。

Status and major advancements in study of hydrocarbon migration

Prior to 1980s,study of hydrocarbon migration had been mainly concentrated in qualitative experiments, understanding of mechanism and geochemical oil-source correlation.Afterwards,it has been diversified mainly in the following 6 aspects:(1)physical simulation with small-scale model-large scale box-like model-realistic simulation; (2)fluid dynamic simulation of hydrocarbon migration-numerical simulation of predominant hydrocarbon migration; (3)study of migration mechanism-study of systems theory;(4)geochemical research of hydrocarbon migration with fluid tracing technologies;(5)study and application of grid model-invasion percolation model;(6)fluid compart- ment-episodic reservoiring theory.The future trends in study of hydrocarbon migration include:predominant path- ways of hydrocarbon migration in carrier beds;building and application of basin-scale invasion percolation models;e- valuation methods of opening and closing of faults;marker features of hydrocarbon inclusion and authigenic minerals; study three-field coupling of palaeo-fluid migration with dynamic and quantitative dynamic methods.
