1 Conclusion The studied formation is a monoclinal structure striking SE and oil-bearing layer developed.

2 The tectonic is simple , which is a monoclinal structure , northwest trend, southeast dip.

3 This paper presents a three-dimensional miscible solute transport model for salt water intrusion into fresh water aquifers , in an inland monoclinal structure.

4 The restricted fold, the unfolded remaining fold, the superposed monoclinal flexures and the coaxial refolded type are in the generalized types.

5 Slope belt of dustpan?like sag may be divided into monoclinal belt and fracture belt as the characteristics structure, reservoir and oil pool etc.
