摘　　要：针对防污染顶封热洗管柱存在封隔器有效期短、容易造成井卡事故的问题,设计了防卡防蠕动热洗管柱。介绍了该管柱的结构、工作原理、技术参数、使用范围和现场应用情况。现场试验证明,该工艺能够有效解决管柱蠕动破坏、井卡等问题,具有良好的推广价值。Against the problem that anti-pollutive and heat-washover string has packer valid short and easily lead to blocking accidents. The anti-blocking and anti creeping heat wash wax string was designed. The tool structure, working principle, technical parameters, using scope and the case of field application are mainly introduced. The field test proved that the technology tc solve a string creeping destruction, blocking and so on, with good promotional value.
