摘要：

The acoustic emission technique is an effective method to determine in-situ stress. and is mainly applied to vertical wells. A new method has been developed to determine in-situ stress for non-directional cores from the inclined well. Using coordinate system transformations and solving nonlinear equations, the method was applied successfully in the Bohai Oil Field.
