It is shown explicitly that the correlation functions of Conformal Field Theories(CFT) which posses the logarithmic operators are invariant under the Borel subalgebra of Walgebra constructed by tensor-operator algebra of sl(2,R). The general expression for three and four-point correlation functions which posses logarithmic operators is calculated.
