Abstract：The skew energy of an oriented graph Gσ is defined as the sum of absolute values of all eigenvalues of its skew adjacency matrix S(Gσ). Two oriented graphs with the same number of vertices are called skew-equienergetic if their skew energies are equal. In this paper， we generalize the definitions of corona and neighborhood corona of oriented graphs and obtain their skew spectra. On the base of these， two methods to construct new non-cospectral skew equienergetic oriented graphs are given.
