In the process of horizontal well developing,especially the horizontal well with relative long hole interval,some problems as unbalanced oil production in each hole interval occur,which leads to bottom water and gas cap coning and limits the oil recovery.This paper sets forth three kinds of techniques for balanced oil production of horizontal well,such as selective perforating,new inflow control devices(ICD) screening and selective oil production aiming at forementioned problems.
