Abstract：
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.
