Abstract
Stress orientations of regional stress field is the main influencing factors for the hydraulic fracture. Most of the hydraulic fracture extend along the greatest principal stress direction, which also affected by geological structure, original faults and faulting plane. Lots of hydraulic fracturing have been monitored in the Tamtsag Basin of Mongolia and Hailaer Basin in the Heilongjiang province of China, which provided information for the will distribution. It is proved that the rule of the greatest principal stress direction except some anomaly directions. It will be great helpful for us to study these anomaly cases. The following of this article will analysis the mechanism of the anomaly directions and reasons for high production.
