摘　　要：东营凹陷滨南地区沙河街组沙三段自下而上发育深灰色泥岩玄武岩碳酸盐岩油页岩岩性序列。研究结果表明 ,水下火山喷溢导致了碳酸盐岩和油页岩沉积 ,玄武岩中的火山矿物和过渡金属对周围烃源岩生烃起到了显著的催化作用 ,从而使烃类早熟和低熟 ;橄榄石蚀变产生的氢气对烃源岩具有加氢作用 ,使其生烃量显著增加。间歇性的火山活动除形成玄武岩储集岩外 ,还导致上覆白云岩破碎 。The lithology sequences analyses showed that the series of dark gray mud basalt carbonate oil shale was developed in Es\-3 of Binnan area in Dongying Depression. The volcanic activities resulted in the sedimentation of carbonate and oil shale. The volcanic materials and transition metals from the basalts were the good catalysts for early maturing and generating hydrocarbon from source rocks. Hydrogen dissolved from basalts had hydrogenation to hydrocarbon source rocks, so that the hydrocarbon generation amount increased greatly. Moreover, volcanic activities could make upper source rocks form good reservoir basalts and typical dolomitic conglomerate.
