Abstract: In order to study the influences of reservoir anisotropy on the productivity of herringbone multi-lateral well，based on the theory of coordination conversion, anisotropic permeability space is transformed into isotropic

permeability space，and prediction is made about the productivity of herringbone multi-lateral wells with percolation model. It can be conclude that：Reservoir anisotropy can change the pressure distribution dramatically. The greater
anisotropy is, the more obvious deflexion there is; The permeability which is perpendicular to the main bore of herringbone multi-lateral well plays the most important role on the productivity. The permeability which parallel to
the main bore of herringbone multi-lateral well plays a secondary role on the productivity. When the anisotropy is clear，the direction of the main bore of herringbone multi-lateral well should be perpendicular to the direction of the
main permeability. When the anisotropy is unknown，a big branch angle should be picked to eliminate the influences of anisotropy.

Key words:

anisotropy, herringbone multi-lateral well, productivity, impact, space transformation
