摘要
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。
Crosswell electromagnetic imaging method is mainly to inspect residual oil distribution in the crosswell space and to service for the exploitation and production (E&P) of oilfields. With the development of E&P of oilfields, crosswell electromagnetic imaging method becomes more and more needful. In this paper, analyzed are dozens of important papers published in Geophysics, transactions of SEG and SPWLA as well as reports from Lawrence Livemore National Laboratory of the United States in recent years, from which the latest advances and developing directions in interwell electromagnetic imaging are generalized. The latest progress is, under 2D condition, the effect of steel casing can be eliminated by mathematical method. The imaging method is available when one well is cased. The developing directions are to study ① the methods for eliminating the metal casing effects under 3D condition, ② feasibility of crosswell electromagnetic imaging method or other methods when two wells are both cased, and ③ the imaging method under fully 3D condition.
