Understanding the dynamics of reconnection jet in the near-Earth magnetotail requires the effects of the Bz component to be included appropriately. In this study, we have conducted three-dimensional hybrid simulations of magnetic reconnection in a two-dimensional magnetotail-like equilibria. Our focus here is on the effects of the width of X-line (Ry),which is controlled by the dawn-dusk extent of the ad-hoc anomalous resistive region in our simulations. We find the shape of the earthward reconnection jets to change according to Ry.In the case of large Ry, the leading part of the reconnection jet is unstable to an interchange instability and bubbles are formed in the near-Earth region. On the other hand, with smaller more realistic Ry,the narrow jet is largely deflected duskward, and the peak Bz value that is piling up at the leading part is substantially reduced.In any Ry case, the magnetic field configurations become much more complicated than those obtained in Harris equilibrium cases and the generated field-aligned current densities are much intensified. A sequence of field-aligned current patterns on the cross-tail section plane at the earthward end of the simulation box is presented and its implication to substorm observations is discussed.
