用地质学、岩石化学、地球化学方法研究了东营凹陷新生代火山岩的分布、产状、岩相及岩石种属、碱度、钾钠类型、岩浆成因与盆地演化、油藏的关系．研究表明：火山喷发既有陆上喷发，也有水下喷发，均以溢流为主；火山岩既有拉斑玄武岩，也有碱性玄武岩，类型为钾质略高的普通型和钾质不高的钾质型；火山岩由幔源原始岩浆在上地幔、地壳岩浆房中演化后喷出地表形成，是盆地强烈拉张下陷和生油层堆积最盛时期的产物；岩浆活动为生油层的熟化和石油的生成提供了热能，火山岩中部分是石油的良好储集层，部分是良好的屏蔽层，与油藏有着密切的关系 The distribution, occurrence, lithofacies, rock types, alkalinity, potassium-sodium type, magmatic origin and basin evolution and reservoir relationship of the Cenozoic volcanic rocks in Dongying Depression are studied by means of geology, petrochemistry and geochemistry. The results show that volcanic eruptions have both onshore and subaqueous eruptions, and are dominated by flooding. Volcanic rocks include both basalt and basic basalt, which are slightly higher in potassium and less in potassium Volcanic rocks formed by mantle-derived primitive magma erupted in the upper mantle and crustal magma chamber and erupted from the earth’s surface. These volcanic rocks are the product of strong stretching and subsidence in the basin and the heyday of oil accumulation. Magmatic activity is the maturation of oil-bearing formations and oil The formation of good reservoirs that provide thermal energy, some of which are oil in the volcanic rocks, and some are good shields, are closely related to the reservoir
