Vitrinite reflectance modeling under overpressure retardation and hydrogen suppression:A case study of source rocks from the third member of Dongying Formation, West Bozhong Sub-depression,Bohai Bay Basin

  • 摘要: 在考虑富氢和超压对镜质组反射率的抑制作用下,对传统仅考虑了温度和时间的镜质组反射率计算模型——Easy%Ro模型进行了重新校正。通过引进富氢校正系数和超压抑制系数,建立起适合双重抑制背景下镜质组反射率计算模型,并利用渤海湾盆地渤中西次凹受双重抑制作用和未受双重抑制作用影响的镜质组反射率Ro实测资料,确定了相关参数。模拟结果表明,在双重抑制作用影响的地层中,镜质组反射率Ro的模拟值与实测值吻合较好,但与Easy%Ro模型的计算结果相差悬殊,双重抑制作用对Ro的影响可达0.2%~0.4%。超压抑制了有机质热演化,导致生烃门限下移和生烃时间延迟,这非常有利于油气晚期成藏。
