THE CORRELATION FRAMEWORK OF FU-YANG OIL LAYERS IN THE EAST OF DAQING PLACANTICLINE

By the triarylated theory system of Exxon sequence stratigraphy,and being tracked the mar-ker bed in the area of basin,which can be contrasted,the Late Mesozoic stratum of the Songliao Basin could be divided into three class sequence.Applying the principle of Cross continental high resolution sequence stratigraphy and according to the alteration of medium-term,short-term and ultrashort-term datum level,the Fu-Yang oil layer can be divided into 3 medium-term datum cycles,8 short-term datum cycles and 39 ultrashort-term datum cycles.And according to the contrast procedure of spot,line and surface,10 main contrast frameworks and 166 accessorial contrast frameworks have been established,and meanwhile a new uniform sequence correlation framework about the east of Daqing placanticline has been established.The established new uniform sequence correlation framework has more definition and high maneuverability.This new sequence correlation framework has laid the geological foundation for nonproducing reserves in the region.
