FPGA在井壁超声成像测井模块中的应用

Application of FPGA in ultrasonic casing imaging module.

针对井壁超声成像测井地面采集模块存在的集成化程度低、调试复杂、动态范围相对较小等缺点 ,利用FPGA优化电路 ,并采用双缓冲技术 ,设计完成了一种基于VXI总线的井壁超声成像测井模块 ,实现了Windows下的井壁超声成像测井信号的实时数据采集。

Because that the original ultrasonic casing imaging module in the surface equipment has the shortages of low integration, complex debugging and narrow frequency dynamic range, an optimized circuit with FPGA is proposed. By using dual buffer technique, a new ultrasonic casing imaging surface module based on the VXI bus has been designed, which can acquire the logging data in real time under the Windows system.
