摘要
为提高开发老区调整井固井质量,开展了水泥浆候凝初期套管振动器提高固井质量技术研究。介绍了振动器系统配套及性能测试,套管振动器系统主要包括地面控制单元、传输电缆、电缆接头和振动器等。配套完成后经室内联调测试表明,地面控制单元输出电压可随工作电流变化自动调节,整套系统实现了远程(5 000m)变频控制,同时满足大电流(额定电流2A)、高电压(AC1 140V)等技术指标,达到了现场应用条件。
To improve the cementing quality of the adjustment well in the old liberated areas,technical research on improving cementing quality by casing vibrator in the early stage of cement slurry solidification is carried out,this article focuses on the vibrator system matching and performance testing.The casing vibrator system mainly consists of ground control unit,transmission cable,cable joint and vibrator etc.After complete matching,the laboratory experiments show that the output voltage of the ground control unit varies automatically with current changes,the casing vibrator system has the ability of remote(5 000 m)frequency conversion control,meets the high current(2 Arated current),high voltage(AC 1 140 V)and other technical qualification,so it reaches the field application condition.
