| 东部富油凹陷油气勘探对中国油气能源发展具有重要的作用。围绕富油凹陷油藏充满规律研究难题，本文以东营凹陷为例，通过 40多个区块近 80个油藏地质要素的解剖，进行了岩性油藏、地层油藏等隐蔽油气藏含油高度的预测，应用数理多元统计方法，拟合了隐蔽圈闭闭合高度与油藏含油高度的定量关系，建立了富油凹陷圈闭石油充满度的计算公式。富油凹陷油气主运移路径上不同类型油藏含油高度的主要影响因素是圈闭闭合高度本身，以洼陷带石油充满度最高，向盆缘明显降低。圈闭石油充满度是盆地生(油源)、运(输导体系)、储三要素时空匹配相互作用机制的综合结果，是评价圈闭有效性更为有效的量化参数。相关认识及预测公式，应用于三合村洼陷也取得了很好的勘探成效，证实了油藏含油高度和圈闭石油充满度用于进行油藏充满规律研究的有效性及其在石油勘探目标评价研究中的现实指导作用。 |

| The exploration of oil and gas in the eastern oil-rich depression plays an important role in thedevelopment of oil and gas energy in China. Focusing on the research problem of the filling law of oil reservoirs inthe oil-rich depression，this article takes Dongying Depression as an example and dissects nearly 80 geological ele.ments of oil reservoirs in more than 40 blocks to predict the oil content height of hidden oil and gas reservoirs suchas lithological reservoirs and stratigraphic reservoirs. Using mathematical multivariate statistical methods，the quantitative relationship between the closure height of hidden traps and the oil content height of oil reservoirs is fit.ted，and a calculation formula for the oil filling degree of oil reservoirs in the oil-rich depression is established. The main influencing factor on the oil content height of different types of reservoirs on the main migration path of oil andgas in the oil-rich depression is the trap closure height itself，with the highest oil filling degree in the depressionzone and a significant decrease towards the basin edge. The oil saturation degree of a trap is a comprehensive resultof the spatiotemporal matching and interaction mechanism of the three elements of basin generation(oil source)， transportation(transport system)， and storage，and is a more effective quantitative parameter for evaluating theeffectiveness of a trap. The application of relevant understanding and prediction formulas in the Sanhecun Sag hasalso achieved good exploration results，the effectiveness of using oil content height of reservoir and oil filling degreeof traps for studying reservoir filling patterns has been confirmed，as well as their practical guiding role in evaluat. ing petroleum exploration targets. |
