摘　　要： 针对交叉偶极阵列声波测井信号的特点,设计了一种以"DSP+FPGA"架构为核心的控制和处理电路。详细介绍了电路的硬件结构和软件设计流程,重点描述了测井数据通信接口和逻辑控制模块的实现,并给出了一种首波提取算法。实验结果表明,该电路在井下高温高压恶劣环境中能够稳定可靠地长时间工作,完全满足工业生产作业的需要。 With the features of cross-dipole array acoustic logging signal, the design of control and processing circuit which is based on ＂DSP ＋ FPGA＂ frame is presented. The hardware structure and the software design are demonstrated. It is emphasized that the way to achieve logging data communication interfaces and logic control modules. An algorithm which is used to detect head wave of cross-dipole acoustic logging signal is also introduced. The results of experiments show that the circuit can operate stably and reliably in high temperature and high pressure environment, and can satisfy the need of industrial production.
