摘　　要：许多井的钻进采用了油基钻井液或无钻井液(空气钻井)钻井,感应测井仪器被研发出来,提供了一种油基钻井液(非导电钻井液)或空气钻井井况下可以测井的一种方法;阵列感应测井仪采用一系列不同线圈距的线圈系测量同一地层,可以得出原状地层电阻率和侵人带电阻率,研究侵人带的变化,对电阻率进行径向成像及侵入剖面的成像;对于砂泥岩薄互层和裂缝性油气层,电阻率在水平方向的分量为低值,而在垂直方向测得的分量为高值。而现有阵列感应测井仪器,测量的电阻率只有水平分量,仅根据水平参数预测砂泥岩产层会出现错误或储层错失的情况,为得到更加精确的地层电阻率,推出了可多维识别地层特性的三维感应测井仪。本文结合较早应用的双感应仪器、正在使用的阵列感应测井仪、客户已经提出需求的三维感应测井仪情况,说明石油工业中感应测井技术的发展。Many Wells were drilled with oil-based drilling fluid or no drilling fluid(air drilling).Induction logging instruments were developed to provide a method in well conditions with oil-based drilling fluid(non-conductive drilling fluid)or air drilling.The array induction logging tool uses a series of coil systems with different coil distances to measure the same formation,which can obtain the original formation resistivity and the resistivity of the invaded zone,study the change of the invaded zone,and conduct the radial imaging of the resistivity and the imaging of the invasion profile.For sand-shale thin inter-bed and fractured oil and gas reservoir,the resistivity is low in horizontal direction,but high in vertical direction for.However,the resistivity measured by the array induction logging instruments is only the horizontal component,and there may be errors or miss in the prediction of sand and shale production based on horizontal parameters only.In order to obtain more accurate formation resistivity,a three-dimensional induction logging instrument which can identify formation characteristics in multiple dimensions is introduced.This paper describes the development of induction logging technology in the petroleum industry by combining the earlier application of dual-induction instrument,the array induction logging instrument in use,and the three-dimensional induction logging instrument that the customer has proposed.
