| This paper based on previous studies,by the full use of existing drilling, logging, seismic and laboratory data to high-resolution sequence stratigraphy theory as a guide, using fine stratigraphic subdivision and correlation technology, the establishment of the study area classification accuracy third-order sequence stratigraphic correlation framework;and the use of heavy minerals, stability factor and features of ancient landforms to determine source direction; through key well-depth study of sedimentary facies marks, divided into facies types, set up logging - Logging phase and the corresponding relationship between sedimentary facies and facies models. Detailed sequence of the three sedimentary facies and sedimentary systems and combined with the law well Sedimentary compared to the analysis, in-depth characterization of reservoir characteristics and the relationship between sedimentary facies; On the basis of the study area combined with the typical lithologic reservoir well and the anatomical analysis of 73 wells, from three-dimensional perspective,predict the orientation distribution of the sand of study area.This study defined the Ganchaigou Paleogene stable source of sedimentary characteristics. Identified during the area Ganchaigou major and alluvial fan - braided - braided river delta - Lakes (slump fan) sedimentary system. For the first time established a region Ganchaigou well - a unified high-precision three seismic sequence stratigraphic framework, and isochronous stratigraphic framework in the area under the Ganchaigou sand distribution was carefully studied, depression combined with Zhaha Spring conditions of source rocks, seals, trap and preservation conditions of analysis, Yue-82 east of the two proposed wells relative uplift beneficial for the distribution of algal limestone reservoir area, Yue Dong 31 wells east of the development of high-quality beach bar sandstones.
