The adaptability of horizontal wells for bottom water reservoirs is analyzed in order to develop reservoir more efficiently. The result shows that the effect of horizontal well on curb water coning is limited , the limit recovery efficiency of it is lower than that of vertical well , and the stimulation treatments for it are difficult to be carried out . It concludes that horizontal wells are not suitable for bottom water reservoir development , but advantageous for edge water reservoirs with thin layer , low permeability and heavy oil .
