轻型数控测井地面数据采集系统设计

Design of Light-Duty Computerized Logging Surface Data Acquisition System

适用于生产测井中产出剖面测井和注入剖面测井的轻型数控测井数据采集系统 ,采用模块化设计 ,将微机PC总线做成开放的数据总线 ,深度系统及不同数据采集测量模块挂接在PC总线上 ,完成对信号的预处理及记录。系统软件采用面向对象的设计方法 ,应用设备无关原则 ,将生产测井过程中不同测井项目所共同具有的操作过程作为共性进行特征抽取 ,在系统软件中以公用模块方式实现资源共享。轻型测井数据采集系统具有较强的测井功能和灵活的扩展性 。

The design idea of light duty computerized logging data acquisition system is introduced in this paper. This system is suitable for the production profile logging and the injection profile logging. It is designed in a way of modularization. The PC bus acts as the opened data buses,connects with the depth control system and some defferent data sampling measuring modules complete the reprocessing and recording of logging data. The system software is designed in a way of OOP(Orient Object Programming). On the basis of the device independence principle,the same operating procedure of defferent production items is extracted to share commonly the resource of the system software by using its public module. This kind of data acquisition system is of the powerful logging function,the flexible expandability and a good ratio performance to price..
