The Sedimentary Miro-facies Of The C84-6 Well Area

The C84-6 well area,Chao Yangou Oil field, Formation of Fuyu, has been studied less before, the formation causes and the exhibition qualities of the sand body are lack of recognition. Therefore, this paper predicted the sand body with post-stack impedance inversion method according to the development status of the C84-6 well area and the sand-mud interstratification geo-characteristics of the Fuyu Fm, making the MCMC inversion based on the results of the CSSI inversion results to analysis qualitatively and descript quantitatively. Based on this, Intergrating the geology data and the previous research results to study the multiple deposit source system, which is controlled by the Tongyu-Baokang and Changchun-Huaide river system, then building the Sedi-model of the depositional environment through the analysis of the core face, logging face and the seismic face to indict the study on the plane and profile facies, lastly, summarizing the depositonal evolution sequence according to the sand body rhythm and the sedimentary environment changing characteristics.
