电磁探伤和多臂井径在检测井下状况时各有优点,但也存在一定弊端。利用电磁探伤和多臂井径成像综合分析,便很好的将二者优点融集起来,提高了检测能力。尤其是随着油田开发的逐年加大,套损井的数量也随之加大。而常见的几种井径仪器却不能够准确精细的反映套管的变化,所以开展井径成像测试技术研究势在必行。而这种测试技术的研究对于减少我国套损井数量,及时检测套管的状况具有卓越性的作用,同时也为生产井作业,提供了全面而又准确的套管全貌。
Electromagnetic testing and dobby track in the detection of underground conditions have their own advantages, but there are also some drawbacks. The use of electromagnetic detection and multi-arm borehole imaging comprehensive analysis, it will be a good blend of the advantages of both to improve the detection capability. Especially with the development of oil fields increases year by year, the number of casing damage wells also increases. However, several common well diameter instruments can not accurately and accurately reflect casing changes, so it is imperative to develop borehole imaging test techniques. However, the research on this test technique is of great significance for reducing the number of casing damage wells in China and for detecting casing conditions in a timely manner, and also provides a comprehensive and accurate casing overall picture for production well operations.
