摘　　要：针对剪切式套管补偿器容易出现销钉提前剪断导致补偿失败的问题,设计了一种通过温控材料融化来控制补偿动作的新型充填式补偿器。优选了80℃熔化的低熔点合金作为温控材料,并对其进行了强度试验,在600kN的压力下不发生位移变形。现场应用表明:该补偿器在注汽和生产过程中能够有效地保护完井管柱,大幅降低了套损井的发生率。Abstract：Problem exists in the sheering casing compensator,caused by advancing breaking of the sheer pin, resulting in compensation failure. So a new filling-up casing compensator was devel oped,which is achieved by the melt of temperature-control material. The low melting point alloy melted at 80℃ was optimized as the temperature-control material,and a strength test have beenmade. This material had no displacement deformation under the pressure of 60T. cation showed that steam injection and Key words, thermal this type of compensator could protect casing effectively in production, resulting in the decrease of casing failure rate The field appli- the process of steam injection and production,resulting in the decrease of casing failure rate.
