  In the present paper, we consider the Cauchy problem of the 2D
Zakharov-Kuznetsov-Burgers (ZKB) equation, which has the dissipative term
$-\partial_x^2u$. This is known that the 2D Zakharov-Kuznetsov equation is
well-posed in $H^s(\mathbb{R}^2)$ for $s>1/2$, and the 2D nonlinear parabolic
equation with quadratic derivative nonlinearity is well-posed in
$H^s(\mathbb{R}^2)$ for $s\ge 0$. By using the Fourier restriction norm with
dissipative effect, we prove the well-posedness for ZKB equation in
$H^s(\mathbb{R}^2)$ for $s>-1/2$.
