     The crack information is of great significance for the exploration and development of low- permeable reservoirs. After principle of reorientation core-cracks with paleomagnetic method was discussed, the operational approach of that was introduced specially. According to vertical and parallel drilling ways of samples, formulas for crack-redirection were elicited with the results of demagnetization. And the method was applied to the cores of a fractured well in Ordos Basin and achieved good results. The research shows that using paleomagnetic method to redirect cores-cracks has the characteristics of easy operation, low cost and high precision. At the same time,the research is reference for the study of Ordos Basin cracks.
