60MHz相位介电测井仪模拟刻度器设计

The Design of the Analogue Calibrator for 60MHz Phase Dielectric Logging Tool

文章以介电测井理论为基础，借鉴感应测井仪的模拟刻度方法，对大庆油田的60MHz相位介电测井仪的模拟刻度进行了研究。参照国内外有关资料，提出了模拟刻度器的设计模型，通过理论分析与计算，建立了一套模拟刻度方法。现场初步试验，该方法取得了一定的效果，为进一步提高仪器的测量精度提供了依据。

At the present,the development of the analogue calibration is very different among the well logging tools. Such as the lateral logging tool and the induction logging tool etc.,the analogue calibrating method is very complete. Although the measuring method and the instrument for 60MHz phase dielectric log have been offered,the analogue calibration for it is not complete. For this reason,based on the dielectric log theory and the analogue calibration of induction logging tool,this paper makes a elementary study for the analogue calibration of dielectric logging tool,offers a designing model of the analogue calibrator,and based on the detailed analysis and calculating,this paper also gives a method of the analogue calibration. At the same time,the test result is relatively successful and the condition for further raising the measurement accuracy of this tool is offered.
