Mathematical and numerical filtration models of incompressible fluid toward horizontal well are build. Influence of hori - zontal well near wellbore features on the well productivity index is investigated. It is supposed that the main parameters of near wellbore damage are size and shape of damage zone, value of permeability damage coefficient on the well bore, profile of permeability change. Influence of collector parameters distribution along horizontal well on the near wellbore formation is investigated. Shown that using of simple near wellbore models may cause significant errors.
