Quantum and classical correlations are studied forWerner-Like States of two-qubit cavity system interacting with a thermal reservoir. Starting from Werner-like states, we have shown that entanglement sudden death and decay of both the quantum discord and classical correlation are accelerated by the different factors: thermal photons, cavity decay and the purity of the initial state. By these factors, the death-start points of the correlations can be controlled and the two-qubit states have no correlations that can be determined. There is no sudden death for quantum discord and classical correlation.
