摘要
电磁感应类测井仪通过测量地层的电导率来对油气层进行评价,而仪器刻度是建立仪器响应信号与地层电阻率关系的主要手段。文章详细介绍了一种用于三维感应测井仪横向分量和交叉分量刻度的斜刻度环设计和应用方法。通过数值仿真和实测结果对比验证了斜刻度环设计的正确性。
Electromagnetic induction logging tools evaluate oil and gas layers by measuring conductivity of formation. Calibration is the pri- mary method of establishing the relationship between the response signal of tools and the conductivity of layers. This paper introduces a de- sign and application method of the tilted calibration loop used for calibration of transverse and cross components of three-dimensional induc- tion logging tools. The design is verifid by comparing numerical simulation data with experimental results.
