小型化油田综合测井信息采集单元

针对油田提出的测井系统要向经济、便携和易于使用维护方向发展的要求,提出了测井地面系统的综合化改进方案。文中详细介绍了综合测井信息采集单元的结构,分析了井下仪传送的各种信号类型,给出了相应信号的处理方案及部分结构和波形图,并描述了与上位机通信的USB接口硬件实现和软件结构。整个系统已经通过模拟测井环境验证,可以进入试用阶段,以进一步观察其效果。

Design and actualization of unit for sampling integrated well logging info

A project of integrated improving on ground well logging system is advanced to satisfy the requirement,advanced by oil field,changing well logging system to economy,portability,and be prone to use and maintenance.This paper introduces the configuration of the unit for sampling integrated well logging info in detail,analyzes various signals which come from underground well logging instrument,gives the scheme and part configuration and wave-form chart for processing corresponding signal,describes hardware actualization and software structure of USB interface for communication with host computer.The whole system has already passed validation of simulant well logging environment and can be put into probation so that the effect can be observed.
