摘要: 渤中凹陷发育较厚的东营组泥岩烃源岩,为了明确该套烃源岩特征及发育模式,通过对渤中凹陷东营组烃源岩样品进行有机-无机地球化学实验、全岩-黏土和孢粉分析测试,评价了该套烃源岩品质,并综合Sr/Cu,Mn/Fe等20种元素比值以及Pr/Ph、伽马蜡烷指数、环萜烷比值、碳同位素、低等藻类化石含量和孢粉组合,分析了东营组形成时期的古沉积环境和古生产力,并建立了东营组烃源岩发育模式。结果表明:①东营组泥岩以石英、长石为主,碳酸盐矿物含量较低,而黏土矿物含量较高,质量分数为30%;②东三段与东二段下部有机质丰度高,达到成熟—高成熟阶段,有机质类型均以Ⅱ1—Ⅱ2型为主;③东三段—东一段均为温湿古气候,水体盐度逐渐变淡,水深逐渐变浅,由东三段高水深(70.1 m)变为东一段低水深(26.7 m),陆源侵入和水体氧化条件呈现逐渐增强的趋势,古生产力高低依次为东三段(高)、东二段(中)、东一段(低);④高生产力、还原保存条件主导东营组有机质的富集,而古气候、水深、盐度和陆源输入对有机质的富集产生间接影响。
