【摘要】 在研究原油通过断裂带渗滤运移机制及主要影响因素的基础上,利用自行设计组装的模拟实验装置,对原油通过不同粒度、泥质含量和倾角的断裂带的渗滤运移特征进行了物理模拟。结果表明,原油通过断裂带的运移速度与断裂带充填物颗粒粒度和断裂带倾角成正比,与断裂带充填物泥质含量成反比;泥质含量是决定原油通过断裂带是否发生渗滤运移的主控因素。利用原油通过断裂带运移速度的大小,可以研究原油沿断裂带运移情况。以车古20潜山油藏断裂为例,利用模拟实验结果,计算了原油通过主要断裂的运移速度,研究了原油通过断裂带渗滤运移的特征,阐明了断裂在车古20潜山油藏油气运聚成藏中的作用。更多还原

【Abstract】 Based on the study of oil percolation migration mechanism through fault zone and its influencing factors, physical simulation was made on the oil percolation migration characteristics through fault zones with different grain sizes, shale contents and tip angles using experiment equipment designed and installed by ourselves. The result indicates that the oil migration velocity through fault zones is directly proportional to the grain size of fault -pack material and the tip angle of fault, and is inversely proportional to shale content of fault - pack material. The shale content is the main factor controlling percolation migration of oil through fault zones. The migration characteristics of oil through fault zones can be studied by the oil migration velocity through fault zones. Taking faults of Chegu 20 buried hill oil reservoir as an example, using the simulation experiment results calculated the migration velocity of oil through main fault and studied the percolation migration characteristics of oil through fault zones. It indicates that faults play a role in migration,accumulation and reservoir forming of hydrocarbon in Chegu 20 buried hill oil reservoir.更多还原
