一种新型遥传测井仪的设计

Design of Telemetry Logging Instrument

遥传测井仪在数控生产测井系统中有着重要作用。针对传统遥传测井仪的缺点,设计了一种新型的遥传测井仪。新型遥传测井仪采用了一种特殊的仪器总线数据传输机制,仪器总线上可同时传送直流电压信号、正脉冲同步信号和负脉冲数据信号;而以单片机为核心组成的遥传短节也采用了新的数据处理方式对仪器总线上的数据进行采集、累加及整理。经实验验证:新型遥传测井仪功耗低、可靠性高,可以代替传统遥传测井仪推广使用。

Telemetry logging instrument （TLI） serves important function in computerized production logging system. Accord- ing to the defects of conventional TLI, a new TLI was designed. This TLI used a special data transfer method on tool bus, the tool bus can carry volts D. C. , positive synehronal pulse signal and negative pulse signal synchronously. Its telemetry cartridge, which was consist of single-chip microcomputer used a new data processing method to collect, accumulate and manage data from tool bus. Experiments prove that the TLI has low power loss, high reliability and can be used instead of conventional TLI.
