Ukraine North times the depression Tongbomiao group development thicker sand bodies , possible reservoir with oil and gas , it is necessary to study its sedimentary characteristics . In this paper, on the basis of a large number of core observation described the latest theories and methods of sequence stratigraphy and sedimentary petrology , combined with logging , seismic and well logging data , stratigraphic Ukraine North times of depression Tongbomiao group sequence stratigraphic framework , sedimentary facies types and distribution characteristics of in-depth study . At the same time , combined with the results of previous studies , using the research results to predict favorable reservoir facies with . Ukrainian north times the depression Tongbomiao group top and bottom interface T3 and T4, respectively are recessed within larger unconformity . Earthquake combined , through well drilling tiered unified seismic interface . The Tongbomiao group is divided into a third-order sequence , four four - layer sequence . Papers start from the lithology , sedimentary structures , logging facies and seismic facies , summed hallmark times depression Tongbomiao group of Ukrainian North deposition phase , determine the study area are mainly developed fan delta phase of the lake , local volcanic rock facies . Application provenance , seismic attributes , stratigraphic distribution characteristics comprehensive analysis phase in a single well , even the well -phase analysis based on four sequence of depositional systems . Based on the above research results , combined with reservoir-cap traps , pointed out that the study area favorable reservoir facies .
