摘要
三分量感应测井系统是一种全新的地层结构探测系统,它可以识别地层的三维特性,是人们认识地层特性,进行油、气储层评价的非常有效的方法。三分量感应测井仪通过布置三组相互垂直的发射-接收线圈对,可直接测量地层的水平电阻率和垂直电阻率,通过测量两个交叉分量还可得出地层的倾角和方位。文章主要从三分量感应系统线圈系的聚焦理论和方法出发,为了消除线圈间的直接耦合,提出了一套全新的线圈系结构设计方案,并对其进行了详细阐述。
A multi-component induction logging system is a new system of detecting the reservoir structure.It can recognize the 3-D characteristic of formation.It is an effective method to evaluate the hydrocarbon.A multi-component induction logging tool provides direct measurements of both horizontal and vertical conductivity by setting three mutually orthogonal transmitter-receiver coil configurations,and it also provides relative dip and tool orientation data by measuring two cross-components.This paper focus on the theory of multi-component induction logging system,and introduces a new coil array configuration of the multi-component induction logging tool,which is effective to eliminate the direct coupling of coils.
