通过分析发表在 Geophysics杂志 ,SEG,SPWL A年会论文集及美国 L awrence L ivem ore国家实验室报告上的几十篇有关最新文献 ,归纳了近年来关于井间电磁成像领域的最新进展及发展方向。最新进展是 :在轴对称条件下金属套管的影响可以通过简单的数学方法消除 ,在一口井存在金属套管时井间电磁成像方法是可行的。发展方向是 :研究全三维条件下金属套管影响的消除方法 ,2口井 (发射井和接收井 )都存在金属套管时井间电磁成像方法的可行性 ,或其它的实现方式 ,以及全三维条件下井间电磁的成像方法。
By analyzing dozens of recent articles published in the Proceedings of the Geophysics Magazine, SEG, SPWL A Annual Meeting and L awrence L ivem ore National Laboratory in the United States, recent advances and developments in crosswell electromagnetic imaging are summarized direction. The latest development is that the influence of metal casing under axisymmetric conditions can be eliminated by simple mathematical methods. Crosswell electromagnetic imaging is feasible when metal casing is present in a well. The direction of development is to study ways to eliminate the effects of metal casing under full three-dimensional conditions, the feasibility of well-to-well electromagnetic imaging methods when metal casing is present in both wells (silos and receiving wells), and other implementations Imaging Method of Crosswell Electromagnetic under Three Dimensional Conditions.
