     Limited oil and gas resource reliability of dark mudstone forecast evaluation data in method. The main formation in northern part of Songliao important foundation of resources eval Basin is uation of K1 d2 deep  the early exploration stage limits the hydrocarbon source rocks of Denglouku  gray mudstone, its distribution is an  tight sandstone gas reservoirs in the northern Songliao Basin. This study combined well to seismic information using quantitative muhicomponent seismic attributes forecast method based on the deposition characteristics to predict mudstone thickness plane distribution in the study area; then consolidated strata deposited thickness plane information, plane information of seismic facies interpretation and well point dark mudstone and shale thickness ratio predict the region plane distribution of dark mudstone and shale thickness ratio; Finally, using seismic prediction of mudstone thickness and the region plane distribution of dark mudstone and shale thickness ratio, we get the plane prediction result of dark mudstone. Prediction results show that there are three large development period of hydrocarbon source rocks of Kid2 black mudstone in Songliao Basin accompanied by other scattered small range of dark mudstone development period, and most of the thickness of those mudstone are less than 70 m,while the biggest thickness is about 350 m. This method ,which based on the well to seismic information and combines the deposit rule to quantitative prediction the distribution of dark mudstone, provides necessary foundation for the reliable evaluation of the resource extent of deep tight sand gas reservoir in northern Songliao Basin.
