摘要
9.5in以上套管声幅在测量过程中,始终存在接箍信号信噪比低或丢接箍的现象,很难达到工程检测要求。文章分析了磁钢的制作工艺,对磁钢、线圈和线路进行改进,重新制作仪器,取得了满意的效果。
In the measurement process of the cement bond logging above 9.5″casing,it always appears that the casing collar locator(ccl)signal-noise ratio is low or missing.it was difficult to meet the engineering testing requirements.In this paper,we make some improvements of the magnet,coil and line,and re-make the tool through analyzing the magnet production craftwork.,We obtained satisfactory result by the actual measurements.
