| 摘 要： | 在对东营凹陷145个岩性油藏含油性统计分析的基础上,结合典型岩性油藏和典型落空圈闭的剖析,对岩性油藏成藏主控因素和成藏模式进行了系统研究。岩性油藏成藏主要受构造沉积背景、烃源岩(围岩)生排烃强度和砂体储集物性等3个因素控制,不同的构造带上具有不同的成藏模式。洼陷带主要发育典型的自生自储自盖的砂岩透镜体油藏,陡坡带主要发育砂岩透镜体、物性封闭、砂岩上倾尖灭、构造-岩性油藏组合,缓坡带、中央背斜带的翼部主要发育砂岩透镜体、砂岩上倾尖灭和断层-岩性油藏。

| Abstract: | The controls on the lithologic oil pools and model for hydrocarbon accumulation in the Dongying depression are explored on the basis of statistical analysis of the oil contents in 145 lithologic oil pools in integration of the case study of representative lithologic oil pools and failured traps.The hydrocarbon accumulation in lithologic oil pools is primarily controlled by tectonic settings,hydrocarbon production and hydrocarbon drainage intensity in the source rocks wall rocks ,and physical properties of reservoir rocks.The models for hydrocarbon accumulation tend to vary in different tectonic settings.The self production-self reservoir-self seal sandstone lenses oil pools occur in the depression zone;structural-lithologic sandstone lenses oil pools with enclosed physical properties and upward declined pinches of sandstone in the steep-slope zone,and fault-lithologic sandstone lenses oil pools with upward declined pinches of sandstone in the gentle-slope zones or on the flanks of the central anticlines. |
