介绍了油井结垢的原因及后果 ,并针对这一问题 ,提出了除垢系统中采用的两种最新开发的技术 ,一种是由连续油管传送的先进射流组件 ,另一种是采用特殊焊珠的特种磨料。并与传统的除垢方法进行了对比。同时 ,介绍了由射流工具和焊珠磨料组成的系统 ,采用连续油管传送干涉技术 ,以清除更多不同类型的垢。发展了爆破系统中大范围除垢的三种方法 :射流爆破技术 ,清除软垢 ;垢爆破技术 ,清除硬垢 ;桥塞爆破技术 ,清除全堵管道中的垢
In this paper, the causes and consequences of oil well scaling are introduced. Two newly developed technologies for descaling system are proposed in this paper. One is the advanced jet flow component delivered by coiled tubing and the other is the use of special welding Beads of special abrasive. Compared with the traditional descaling method. At the same time, a system of jet tools and bead abrasives is introduced, using a coiled tubing transfer interference technique to remove more different types of scale. Development of a wide range of blasting system in the three kinds of descaling methods: jet blasting technology to remove soft scale; scale blasting technology to remove hard scale; bridge plug blasting technology to clear the scale of the pipeline full scale
