Octupole deformation description of medium and heavy nuclei regions has been systematically carried out by using the particle-number-conserving microscopic approach [1, 2]. The commonly used effective interaction Skyrme energy density functional has been used for particle-hole channel. The low multipole components of the pairing-plus-multipole two-body interaction have been neglected, whereas the high multipole components are approximately represented by a density independent $\delta$ interaction to describe the paring correlations. The obtained results are compared with previous HF+BCS ones. [1] T. V. Nhan Hao, J. Le Bloas, M. H. Koh, L. Bonneau, and P. Quentin, Int. J. Mod. Phys. E 21 (2012) 1250051. [2] T. V. Nhan Hao, P.
