Directed by the modern advanced theories, views and methods such as sedimentology, cyclic stratigraphy and reservoir geology etc., starting with stratigraphic classification and correlation, this thesis expounds the sedimentary framework and the predominant types of sedimentary facies of Member Jia-2. And three kinds of facies and more the eight kinds of subfacies have been recognized on the basis of field profile observation, core data, a large amount of slice identification as well as single well lithology and sedimentary facies analyses about seven key well.Through the analysis of the sedimentary facies of individual well and the features of correlation profiles of two wells,the vertical and lateral development regulation of sedimentary facies of Member Jia-2 Formation is clarified. Using single factor analysis method, indexes, including the thickness of the whole formation, grain rocks, dolomite, limestone, and the individual bed thickness that of the whole formation ratio, have been selected to analyze quantitatively the sedimentary facies of different phases. Furthermore, together with the regional sedimentary background, the plane distribution characteristics of sedimentary facies respectively have been shown clearly according to the dominant facies. And the development and evolution models of the facies have also been established. By means of thestudy of diageneses, the reservoirs' formation and development mechanismshave been discussed, and as a result, the establishment of reservoir development model appears. Finally, based on the characteristic of reservoir and the predominant factors what control the reservoir development, this paper have done some estimation and prognosticated the advantageous distributing of the vertical and horizontal reservoir for the secondary exploration in member Jia-2 Formation in transitional district of central and southern of Central Sichuan Oil and Gas Field.
