Stratigraphic correlation is the most important basic work in oil and gas exploration and development, Scientific and reasonable stratigraphic correlation is the premise of developing fine reservoir description, and it is also the guarantee to improve the efficiency of oilfield exploration and development. Whether the facies controlled cycle isochronous correlation method or the high-resolution sequence stratigraphic correlation method (Yan Ke, et al, 2011), both are based on the same lithology to conduct stratigraphic cycle correlation. Because of the complicated sedimentary environment and the great change of lithology in the continental basin, in especial the salt lake basin, the change of lithology often happens in Stratigraphic cycle. In the stratigraphic framework, where there is no sand frequently correspond the salt. Tankou oilfield is located in the northern part of the Qianjiang Sag, the footwall of the Qianbei Fault. Because of the complex structure and the rich geological phenomena, the strata has its unique characteristics, the phenomenon of the mix of the sandstone and salt rock is Significant. In response to this phenomenon, based on the study of the characteristics of structural evolution and the sequence characteristics of the salt bearing strata in Saline Lake basin, this paper solves the problem. *
