摘要
针对目前还在继续使用的SJC - 1C水泥胶结综合测井仪器的套管接箍信号探测部分 ,提出了由供电探测到不用供电就达到测量目的的一种无源探测方法。从理论上阐述了这一方法的可行性、优越性及实用性 ,并结合原有井下仪结构及地面信号处理系统 (EXCELL - 2 0 0 0 )的特点 ,详细描述了改进过程及具体步骤 ,并通过改进后的应用效果展示了这一改进的实用性。
A non-power detecting method is proposed based on the analysis on the casing collar signal detecting component of SJC-1C cement bond sythetical tool. The possibility, superiority and practicability of this method is interpreted theoriatically. According to the characteristics of the original downhole tool′s structure and the uphole signal processing system (EXCELL-2000), the detailed improving process is also given.
