| 摘 要： | 通过数值模拟与物理模拟分别研究了油气在聚集后散失过程的流体流动机制。流体场的力学机制决定了油气在散失过程中的差异性以及油气层自身流动的独立性。研究表明:一个局部高点的石油泄漏对另一个高点石油保存影响不大或基本没有影响,虽一个高点泄漏而两个高点的天然气均能被产出,遭受破坏的聚集带油藏一般比较孤立而气藏却成组分布。这对同一聚集带上的油、气勘探有重要的指导意义。

| Abstract: | The geological models of oil-gas flow mechanical simulation were studied for the different oil-gas dispersion processes after their accumulation by use of both digital and physical simulations. The mechanism of fluid field decided the difference of oil-gas in a dispersion process and the flow independence in oil and gas layers. The main results were as follows. 1)Petroleum leakage at a local high point little affected petroleum preservation of another high point, or only had small influence. 2)Although leakage at one high point, the natural gas in both the high points could be produced. 3)In an accumulation belt which experienced disruption, the distribution of oil reservoir isolated generally, while the distribution of gas reservoir often grouped. These results must have an important theoretical significance for guiding the oil-gas exploration and development activities in the same accumulation belt, which was demonstrated to be a good direction in the Ordovician oilfield in Lunnan, the Tarim Basin. |
