The binding energy of Cooper pairs has been calculated for the case of d-wave symmetry of the superconducting gap in layered cuprate superconductors. We assume that Cooper pairs are formed by the short range potential and then derive the binding energy in the form Delta _{{mathbf{kq}}} = Delta _x ({mathbf{q}})cos k_x a + Delta _y ({mathbf{q}})cos k_y a + Omega _x ({mathbf{q}})sin k_x a + Omega _y ({mathbf{q}})sin k_y a, where q is a totalmomentumof the pair. Numerical solutions of the self-consistent system of the integral equations for quantities Delta _x ({mathbf{q}}) , Delta _y ({mathbf{q}})and Omega _x ({mathbf{q}}), Omega _y ({mathbf{q}})along different lines in qx, qy plane have been obtained. Anisotropy of the depairing total momentum (or depairing current) has been calculated.
