阳离子淀粉作为以淀粉为基本原料合成的绿色化学品，应用越来越广泛。本文简要概括了国内外阳离子淀粉的合成工艺，包括湿法、干法和半干法。综述了阳离子淀粉在油田生产中，尤其是其作为钻井液处理剂、油田污水处理剂、调剖堵水剂和驱油剂的应用研究进展。展望了阳离子淀粉在我国的发展前景，指出了大力开展阳离子淀粉研究的重要意义。

Cationic starch was a green chemical which synthesized using starch as primary raw materials and was more and more widely used nowadays. The preparation techniques of cationic starch at home and abroad including wet process, dry process and half-dry process were briefly summarized. The applications of cationic starch in oilfield，especially the applications as drilling fluid additive, water treatment agent, profile control and water shutoff agent and oil-displacing agent were reviewed. Development prospect of cationic starch was discussed, and the important practical significance of developing the study of cationic starch greatly was pointed.
