| 摘 要： | 油源对比是含油气系统划分的基础.针对东营凹陷沙三中、沙三下和沙四上三套有效烃源岩在地球化学特征上的差异,探讨了东营凹陷内三套烃源岩与已知原油之间的空间对应关系及其成因.以油源对比为依据,将东营凹陷划分为沙三中-沙三中亚段(!)、沙三下-沙二、沙三段(!)和沙四上-沙四、沙二段(!)3个含油气系统.分析结果表明.3个含油气系统中已发现的油气藏在空间上具有明显的环状分布特征,其成因模式受控于输导要素组成、油源断层分布位置、烃源岩内砂体的发育规模以及断-砂空间组合等;其中,油源断层和砂体的空间组合关系对东营凹陷不同成因油气藏的形成与分布起主控作用.

| Abstract: | Oil-source correlation is the basis of the petroleum system research.The relationship of source rocks and petroleum in Dongying depression is discussed by analyzing the geochemical characteristics of source rocks,and three petroleum systems(Es3z-Es3z(!),Es3x-Es2/Es3(!)and Es4s-Es2/Es4(!))are classified for the Tertiary of Dongying depression according to oil-source correlation.Study shows that the oil and gas patterns of these three petroleum systems are circular and their formation is controlled by migrati... |
