摘要: 为研究鄂尔多斯盆地富县地区延长组长7烃源岩特征及生烃潜力,开展了岩心分析、测井研究、干酪根镜检、镜质体反射率(Ro)测试、岩石热解分析、气相色谱及色谱-质谱分析。结果表明:(1)富县地区长7烃源岩平均厚度为45 m;总有机碳(TOC)质量分数平均为5.94%;生烃潜量(S1+S2)平均为13.1mg/g。(2)有机质类型以Ⅰ和Ⅱ1型为主,烃源岩母质类型以低等水生生物为主,并含部分高等植物,沉积时水体为还原环境。(3)镜质体反射率平均为0.76%,生物标志化合物中C31藿烷22S(/22R+22S)、20RC29αββ(/αββ+ααα)和αααC2920S(/20S+20R)平均值分别为0.52、0.62和0.49,反映有机质演化进入生油高峰阶段。(4)平面上,富县地区中部和西北部长7烃源岩厚度大、生烃能力更强,为下一步勘探的有利区带。该研究成果对鄂尔多斯盆地富县地区的精细勘探具有重要指导作用。
