| 摘 要： | 由于重力作用，水平井的侵入带已不再是对称于井轴的圆柱体，将侵入带效为圆柱体，仪器位于偏心轴上来逼近实际模型。以偏心点电流泊的电位格林函数为基础，求解测井响应并绘制侵入校正图版，由此可求得原状地层电阻率和等效侵入半径。

| Abstract: | Because of the gravity, the invaded zone in horizontal well is not a precise cylinder which is symmetrical about the hole axis. In order to approach the actual model, we regarded the invaded zone as a cylinder in which the tool is located in an eccentric position. Based on the potential Green function of an eccentric point source, responses of dual-laterolog have been calculated and an invasion correction chart is made according to the numerical results. Therefore, the resistivity of the original bed and the equivalent invasion radius is estimated. |
