Detailed theoretical calculations are performed for the 4f and 5p inner-shell excitations of W-W3+ ions using the multiconfiguration Hartree-Fock method in order to better understand the origin of the XUV photoabsorption spectra of W atoms from the dual laser-produced plasma experiment (Costello et al. J.Phys. B 24 (1991)5063) and the spectra of photon-induced single ionization of Wq+ ions (q =1,2,3) (Miiller et al.Phys.Scr.T144 (2011) 014052) from photon-ions merged beam experiments,respectively.Two broad and strong resonances in the experimental spectra have also been theoretically identified mainly from 5p-5d resonance.The 4f-5d,6d and 5p -6d transitions also make a small contribution to each spectrum,which are superimposed on the 5p-5d transition arrays. Based on the assumption of a normalized Boltzmann distribution among the excited states,we succeed in reproducing spectra which are in good agreement with experiments.
