英国SONDEX公司MITOMTT组合测井仪对检测套管内径和壁厚的变化有很高的诊断能力,其配套的解释软件WIPER可对解释结果作统计分析,WIVA绘图软件可绘制出三维成像图,直观反映管壁腐蚀、穿孔的位置和状况。本文介绍了MIT/MTT的测井原理,结合海外某油田一口井的实测资料,介绍了MIT/MTT测井的资料分析及其结果,并指出了MIT/MTT优势和使用范围的局限性,假信号及其处理,以及受井况的影响等问题。
British SONDEX company MITOMTT combination logging tool to detect changes in casing diameter and wall thickness has a high diagnostic capacity, the interpretation of the software WIPER Interpretation of results for statistical analysis, WIVA mapping software can draw a three-dimensional imaging, visualization Reflect the pipe wall corrosion, the location and status of perforation. In this paper, the principle of MIT / MTT logging is introduced. Based on the measured data of a well in an overseas oilfield, the data analysis and results of MIT / MTT logging are introduced. The advantages and limitations of MIT / MTT are also pointed out. Signals and their handling, and the effects of well conditions.
