Horizontal well technology can improve development effect and benefit of oil and gas fields,so it has been developed rapidly in the world.The staged water control completion technology is developed in this paper in terms of the bottom water reservoir,which can effectively alleviate the bottom water coning and extend the period of low water cut oil production;for unconsolidated sandstone reservoir, the open-hole gravel pack completion technology is developed to solve the sand problem for sand reservoir;for the horizontal well in low permeability reservoir,the open-hole staged and cementing staged fracturing completion are integrated to improve output of the wells.
