李会银,鞠晓东.核测井仪井下集成电子系统的设计.测井技术,1998,22(3):208~211介绍一种以单片机为核心的核测井仪井下信息采集、处理及数据传输电子系统的设计方案。该系统可对岩性密度和自然伽马能谱进行多道幅度分析,并对补偿中子测井信号及所有井下常规模拟信号、脉冲信号进行数字化采集。数据传输采用与阿特拉斯3508遥测短节兼容的半双工曼彻斯特编码。所述设计已在Φ89和Φ76两种直径的井下组合仪器中实现。
A downhole data acquisition, processing and transmission system for nuclear logging tool based on microprocessor is described.By this system, the pulse height analyses for z density (Z DEN) and natural gamma spectroscopy log can be made.Compensated neutron log (CNL) and other conventional logging analog signals, pulse signals can be acquired. Data transmission unit adopts half duplex Manchester encode decode mode, which is compatible with Atlas 3508 telemetry cartridge. The scheme has been realized for both Φ89 mm and Φ76 mm downhole tools.
