基于F P GA的泥浆电参数测量系统设计

针对石油测井过程中实时获取钻杆周围地层图像信息的问题，详细介绍了一种基于现场可编程门阵列(FPGA)的泥浆电参数测量系统设计和实现过程。整个系统采用模块化设计，主要包括FPGA控制器、幅度/相位检测器、信号调理电路以及直接数字频率合成信号发生器。该系统突破了传统测量泥浆电参数的思路，通过测量盛有泥浆的环形容器复阻抗的方式间接获取泥浆的电参数。实验结果表明，该系统满足了石油测井过程中的实际应用需要。

Mud EIectricaI Parameters Measurement System Based on FPGA

In order to get the real-time image information of the the drill pipe,the mud electrical parameters measurement system based on FPGA is proposed.The system is consisted of FPGA controller,amplitude/phase detector,signal conditioning circuit and direct digital frequency synthesis signal generator,which adopts modular design.The system measures the complex impedance of the circular container filled with mud,then indirectly acquires the electrical parameters.The experiment results show that the system can meet the application needs of the actual logging engineering.
