摘　　要：阐述了一种新型井下存储式电子压力计的研制,由井下仪器和地面处理软件两部分组成。井下仪器由单片机和A/D采样器组成,可以利用极低的功耗实现仪表设备的运行,延长电池的使用寿命;地面处理软件通过读取井下仪器存储的数据,实现回放、显示、分析等功能,同时将温度传感器外置,缩短温度测量延时。测试数据表明:该压力计在设计要求的压力、温度工况下,精度均可以达到0.05%以内,能够满足井下测试的要求。The development of a new downhole storage electronic pressure gauge is described.It consists of two parts of downhole instrument and ground processing software.The downhole instrument s composed of single chip microcomputer and A/D sampler.The operation of the instrument can be under very low power.The service life of the battery is prolonged.Through reading the data stored in the underground instrument,the functions of playback,display and analysis can be realized by the ground processing software.Time delay of temperature measurement s shortened with externally installing the temperature sensor at the same time.The test results show the precision of the pressure gauge can reach 0.05'within the designed range of pressure and temperature,the requirements of downhole testing can be satisfied.
