摘　　要：国内碳酸盐岩储层埋藏深,呈现非均质性强、温度高、缝洞发育等特征,给水平井增产改造带来了困难。通过调研和分析国内外水平井分段改造技术,介绍了深层碳酸盐岩储层水平井无工具分段改造技术、机械工具分段改造技术、酸液体系的研究现状和现场应用情况,形成适合深层不同储层的水平井分段改造技术,对加快深层碳酸盐岩储层高效开发具有重要的指导意义。The carbonate reservoir which has characteristics of strong anisotropism, high temperature, developed cavern buried depth in China. It brings difficulties to stimulation for the horizontal well. Through the investigation and analysis on the staged transformation technology for the horizontal well at home and abroad, this paper introduces the research status and field applications of no tools staged transformation, mechanical tools staged transformation and acid system for the deep carbonate horizontal well. The transformation technology of the deep horizontal well which is suitable for different reservoir is formed. It is of great significance to accelerate the efficient development of deep carbonate reservoir.
