The Deep Structure Study And Fundus Prediction Of Binbei Area In North Songliao Basin

The area of Binbei area in North Songliao Basin is very much larger, and the exploration degree is comparatively lower.The previous study of this area show that the dark mudstones in lower and middle depth layers are comparatively undeveloped, the Carboniferous -Permian shale are developed at large and have strong capability to bear hydrocarbon.Through the more thorough study of the deep structure and Fundus lithology of Binbei Area in North Songliao Basin, we consider that there have six basic structure modes and two structure styles in the deep layers of Binbei Area. In the LinDian Area, the Carboniferous System and the Permian System layers have obvious phenomena of upthrust and overturn, the fundus ruptures are transform ruptures with more period extrusion and outspread, these ruptures control the spread of structure units and the development of sediment systems, the fundus lithology are mainly shallow metamorphic rocks of the Carboniferous System and the Permian System, secondly are the gneiss of the Precambrian and the intrude rocks of stage of Haixi and stage of Yanshan, among the developed area of shallow metamorphic rocks of the Carboniferous System and the Permian System there have determinate capabilities to bear hydrocarbon.
