As the exploration and development deepening, the requirement on the classificational accuracy of deposition time units becomes higher and higher, and the sequence stratigraphic division of long-time scales is not enough to meet the demand of development. But the research methods of high-resolution sequence stratigraphic framework have highly detailed and accurate characteristics, so it is a new developing direction of sequence stratigraphy. Combining logging, core, seismic and outcrop data, clearing the classification principles of high-resolution sequence stratigraphic framework and giving a reasonable plan, close skeleton section is established. From the standard well, firstly the strata contrast of the wells in backbone profile is accomplished, and then the wells out of backbone and the backbone of the adjacent sections are compared. This method not only ensures a unified standard of the contrast in the region, but also ensures the high resolution of the contrast.
