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.%水平井技术可以提高油气田开发效果和效益，所以水平井技术在世界范围内得到了迅速发展。本文针对底水油藏水平井，配套集成了分段控水完井工艺，有效缓解了底水锥进，延长了低含水采油期；对于疏松砂岩易出砂油藏，自主研发了裸眼砾石充填完井工艺，解决了粉细砂油藏的防砂问题；针对低渗透油藏水平井，配套集成了裸眼分段压裂完井技术和固井分段压裂完井技术，达到了增产的效果。
