摘　　要：地层压力测试技术能够为油田地质和油藏工作者提供重要的储层信息。FET -3 0 0 0地层压力测试地面系统采用先进的CPLD可编程逻辑器件和单片机技术 ,减少硬件电路 ,有效地提高了该系统的集成度。该系统传输方式采用标准的双相位传输格式 ,数据传输速率可达 10 0kb/s ;信号传输采用半双工通讯方式 ,在计算机的指令控制下 ,实现数据采集、格式编排和传输。应用表明 ,该系统与进口的CSU地面系统相比 ,无论在测井信号采集 ,还是在对井下仪器控制及系统的辅助功能方面 ,都显示出良好的可靠性和灵活性 ,有效地降低了硬件电路中的故障率和设备成本 ,收到了较好的应用效果。The application of formation pressure testing technique can provide significant information for both field geologists and reservoir experts. The repeat formation tester is an effective downhole tool. Howerer,its application and extensive use are confined by expensive imported surface equipment and there is no special equipment matched with it. So FET-3000 surface system is developed,and advanced CPLD and single chip processor are used in the system,the system with satisfactory field application. The structure,circuits,dual phase coding signal,transmission mode and advantages of the system are introduced,and the principle of signal acquirement and its acquiring course,as well as the principle the system controls the downhole tool are described.
