摘　　要：双侧向测井是裸眼井测井常规项目之一,在油田测井中已得到了广泛的应用。文章介绍的KG2006恒功率双侧向测井仪按设定的功率控制曲线进行工作,通过电压、电流同时响应地层电阻率的变化,得到地层的两条深浅电阻率曲线。能同时测量侵入带与原状地层电阻率,可直接挂接3700、5700地面系统,重点解决了川渝地区碳酸盐岩、高矿化度泥浆的高阻层、大井眼等恶劣井眼条件下测井难题。文章介绍了该仪器的基本工作原理,技术指标,软、硬件实现方法与实际应用。DDL is one of the traditional items of well logging,which is widely applied in oil fields.This article introduces KG2006 constant power dual lateral logging tool which acquires the resistivity of the deep zone and the resistivity of the shallow zone under a designated power by the voltage and current varying simultaneously with the altering of the zone 's resistance.The tool is a valuable new logging tool which can acquires resistivity of the invaded zone and resistivity of the original zone at the same time under the control of CLS3700 or ECLIPS5700.It has successfully solved the problem that it is difficult to acquire resistivity of the resistive bed on the condition of salt mud,big borehole in carbonate reservoir of Sichuan Chongqing gas field.This article introduces the theory,equipment specifications,the methods in the software and hardware and the application of the tool in the oilfield.
