主要介绍了最近几年出现的连续油管压裂新技术，首先介绍了准确定位压裂技术、多层同时压裂技术、漏掉产层压裂技术中使用的井下工具组合、现场操作方法以及现场应用效果等，然后对其经济性和存在的问题做了分析，最后对在国内开展连续油管压裂进行了可行性分析。

Coiled-tubing fracturing technology has occurred for more than ten years and it forges rapidly ahead through the field
application. In this paper, the update technologies of coiled-tubing are introduced, which includes the downhole tools
assemblage, field operating method and field application used in the pinpoint fracturing, simultaneous multiple fracturing and
bypassed fracturing. The economic analysis of the coiled-tubing fracturing is done and the existing questions are also discussed.
At last, the feasibility of coiled-tubing fracturing technology is analyzed.
