Most of carbonate reservoirs exists bottom water in China. Due to the coning of bottom water，water cut of oil wells rises rapidly，causing to water flooding in severe cases. Controlling the rapid breakthrough of bottom water in carbonate reservoirs has become one of the hot issues in recent years. Therefore，it is necessary to sort out and summarize the bottom water control technology of carbonate reservoirs. The water production characteristics and mechanism of oil wells in carbonate bottom water reservoirs，water control technology and water control or water blocking materials were explained. The research progress and problems of water control materials and technics such as inorganic materials，polymer solutions or gel systems were summarized. The nanocomposites applied into water control in low-permeability carbonate reservoirs were prospected.
