摘　　要：张中庆，张庚骥．阵列型感应测井的多参数反演．测井技术，１９９８，２２（５）：３２１～３２６提出采用Ｍａｒｑｕａｒｄｔ法和ＳＡＭ－ＦＦＨＴ反演阵列型感应测井的资料。计算结果表明，足够多的感应测井曲线，能够可靠地获得二维电阻率剖面。文中给出两种反演方法：块状均匀介质的多参数反演和象素级反演。其中象素级反演算法适用于纵向电阻率和径向电阻率缓变的地层。A new algorithm is put forward to inverse multi array type induction logging curves using Marquardt method and SAM FFHT. The computation result shows that satisfying two dimensional resistivity profile can be obtained by using sufficient induction logging curves. Two algorithms are employed to inverse the massive homogenous media and pixels of resistivity profile. The latter is suited for the formation with slow changing resistivity in vertical and radial direction.
