| 摘 要： | 对于双侧向测井反演，本文将广义逆反演方法用于消除侵入影响的三参数(侵入半径、侵入带电阻率、原状地层电阻率)反演中。通过实际多口井连续曲线的反演处理表明，本文提出的反演方法令理而且有效。同时，广义逆方法提高了反演计算的稳定性和精度。对低阻油层实际资料的处理结果与试油结论一致。

| Abstract: | During the inversion of the dual lateral log, The generalized inversion method is used to invert the three parameter (the radius of the invasion zone, the resistivity of the invasion zone, the resistivity of the destination formation) and eliminate the affect of invasion zone. The result of processing dual laterolog successive curve indicate that the inversion method performance well. At the same time the generalized inversion method enhanced the stability and the accuracy. The result of processing the actual log data of the low resistivity reservoir agree with the conclusion of the oil digging. |
