摘要
为了研究电阻率测井方法中电极位置和侵入带对测井响应的影响,本文讨论了有侵入带井眼的Green函数问题,并用本征函数展开法求出了精确解,进而说明在无井眼均匀地层和有井眼均匀地层两种特殊情况下所求得的精确解与已有理论结果完全相同。
In this paper, the authors consider the Green's function in the borehole with a invaded homogeneous formation for studying effects of the position of electrodes and invaded zones on the responses of resistivity logging. Then, this problem is solved exactly by eigenfunction expansion.It is showed that the solution is same exactly as the known one in the homogeneous formation with and without a borehole.
