我国碳酸盐岩油藏大多底水发育，由于底水锥进导致油井含水快速上升，严重情况下造成油井水淹。控制 碳酸盐岩油藏底水快速突破成为近年来研究热点问题之一，因此有必要对碳酸盐岩油藏底水控制技术进行梳理 和总结。综述了碳酸盐岩底水油藏油井出水特征及机理、控水工艺以及控水或堵水材料，总结了无机材料、聚合 物溶液或凝胶等控水材料及工艺的研究进展及面临的问题，展望了纳米复合材料在低渗碳酸盐岩油藏控水中的 应用前景。图7参60

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.
