第一节油气藏中的静态状况 、油气水的分布状况 The distribution of oil and gas in reservoirs 如果在储集层中同时存在油气水时,由于气体最轻,将 占据构造的顶部,称为气顶;石油则聚集在稍低的翼部,而 密度更大的水则位于油的下部。 油气藏中油和水的接触面称为油水界面,投影到水平面 上即为含油边缘。严格来说,含油边缘应划分为含油内缘和 含油外缘。油气界面与储集层顶面的交线称含气边缘。 In reservoir the oil-water contact surface is called oil- water interface, and it shall be the oil-bearing boundary when projected onto the horizontal planar. Strictly speaking oil-bearing boundary should be classified as inner boundary and outer boundary. The intersecting line of oil-gas interface and reservoir top is called gas boundary
