摘　　要：在简述连续管喷砂射孔填砂环空压裂技术原理与技术特点的基础上,阐述了哈里伯顿公司CobraMax系列技术在直井和水平井中的典型应用以及在煤层气和页岩气压裂中的应用。介绍了填砂技术的3种基本类型及其发展过程,并对诱导砂堵填砂技术及其发展进行了系统分析。结合国内应用连续管喷砂射孔填砂环空压裂技术的情况,提出了发展建议,指出国内填砂技术与国外主流技术的差距是制约该技术在国内有效应用的主要原因。On the basis of a brief description of the principle and technological t^ature of coiled tubing sandblast perforation sandpack annular fracture technology, the research and application of Halliburton Company＇ s CobraMax series of teehnology were expounded, including their tyt）ieal applieation in straight well and horizontal well as well as their application in coal bed gas and shale gas fracture. Three basic types of sandpack technology and their devel- opment process were introduced. A systematic analysis of induction sand plug sandpaek technology and its development was conducted. In combination with domestic application of coiled tubing sandblast perfbration sandpaek annular fracture technology, the development suggestion was given, pointing out that the gap in sandpaek technology is the main reason for restricting the effective application of the technology in China.
