摘要
通过地震反演获取鄂西渝东地区东岳庙段泥页岩段的速度场数据,再转化为泥页岩的孔隙度,进而预测镜质体反射率,最终获得页岩有机质热成熟度。现场应用表明,这种通过地震反演速度场预测镜质体反射率的方法对于勘探程度较低尤其是钻井稀少的地区有着较高的实用价值。
For the Dongyuemiao member of the lower Jurassic in the west of Hubei and the east of Chongqing,shale strata velocity date was obtained by seismic inversion,and then converted into shale porosity,the vitrinite reflectance Rowas calculated,and the shale strata thermal maturity of organic matter can be obtained.To device vitrinite reflectance Ro by seismic inversion of velocity field,it has practical value in t exploration.
