油气二次运移和聚集实验模拟研究现状与发展

实验模拟是油气二次运程和聚集研究的重要手段和方法，几十年来，许多学者进行了大量的模拟实验研究，确定了油气二次运移和聚集的一些机理，深化了油气成藏和分布的认识，目前实验模型主要有一维模型、二维模型、三维模型和微观模型，油气二次运移和聚集实验模拟的发展趋势主要表现在：（1）研究内容不断深入，由单纯的机理研究向为数值模拟提供参数以及实际油气藏成藏动力学模拟发展；（2）研究方法不断改进，实现宏观与微观实验模拟以及实验模拟与数值模拟的结合；（3）实验设备更趋于先进，实验模型向大型化、多功能化和自动化方向发展，观测手段也日趋现代化。

STATUS AND ADVANCES OF THE STUDIES ON THE EXPERIMENTAL SIMULATION OF SECONDARY HYDROCARBON MIGRATION AND ACCUMULATION

The experimental simulation is one of the important research means for seconday hydrocarbon migration and accumulation. Much expermental simulation has been done by many researchers in the last decades of years. These researches determined some mechanisms of secodary hydrocarbon migration and accumulation and deepened the understanding of formation and distribution of oil-gas reservoir. At present, there are four kinds of exeperiment models: one-dimentional model, two-dimentional model ,three-dimentional model and jmicroscopic model. The advances in the expermental simulation of secondary hydrocarbon migration and accumulation are as follows:(1)the research fieds will be increasingly widsned from the mecedsm study to providing paramters for numerical modeling and the dynamic simulation of actual formation of oil-gas reservoir; (2)the research method will be increasingy improved by the linkage between macmecopic and dricroocopic experiments, as well as experiments simulation and numerical modeling; and (3) the exeperimental instrtnnents will be increasingly advanced. The experimental model will develop toward large-scale, multi-functional, and automatical, and the minitoring instruments toward modernizational.
