摘要

This paper discussed the connotation, types of the accommodation structure, proposed a new classification scheme that accommodation structure can be divided into two categories, the transform fault (shift fault) and the transfer zone, and graded classification by its control effect on tectonic units.According to shapes, the transfer zone can be divided into "bump, slope, horst, graben and fault terrace"five types.On the basis of the actual data of Hailaer basin, the author analyzed in detail the characteristics and identification marks of transform fault and transfer zone, discussed the origin of the accommodation structure.The author consider that the differences of the basin basement structure would be the main factors to lead to formation of the primary, secondary accommodation structure.Finally, author analysis the relationship between accommodation structure and oil and gas.The results of the study would be important to structure research in the streching basin.
