Seismic Prediction Method for Dark Mudstone Thickness of the Second Member of the Denglouku Formation in Northern Songliao Basin

Abstract:

The hydrocarbon source rocks in Denglouku formation of Northern Songliao Basin are mainly the grey mudstones in Deng 2 member. Combined with well and seismic information, this paper forecasts the mudstone thickness distribution of study area applying multiple seismic attribute quantitative prediction based on sedimentary characteristics. We also predict the plane distribution of dark mudstone-mudstone thickness ratio with stratigraphic sedimentary thickness information, horizontal result of seismic facies interpretation and dark mudstone-mudstone thickness ratio materials of well point. Eventually, we obtain the plane dark mudstone prediction result. Analysis indicates that the source rocks of Deng 2 member in Northern Songliao Basin mainly consist of three larger dark mudstone development areas and other sporadic small-scale development areas adjacent, which have the maximum dark mudstone thickness of about 357m located near Songji 6 well.
