Abstract: Several elements that can make the dip data interpretation models complex are summarized under the extensive
structure setting in this paper. They should be integrated with the relative sedimentary facies，lithologic character，borehole
condition and wireline logging time，et al. Because the structure styles in the extensive basin are complex and diverse，the
dip data interpretation models also have multiple solutions. Several dip data interpretation models under different structural
location of listric fault depending on the geologic section were described，and a dip data interpretation example that one dip
pattern can correspond with several structural styles was analyzed. So geology model is to be obtained by combining with dip
model and geology background and other data，especially，seismic profile.

Key words: extensive structure, dip data, structure interpretation, multiple solution, dip model
