摘要： 概述了采用网络互联的专用数控测井地面系统——SGX3数控测井系统的整体设计思路。SGX3数控测井系统分下位机和上位机部分，两者通过实时网络通信方式进行数据传输。下位机现场测井工作站采用PC-104嵌入式PC，专门负责测井数据的采集。上位机采用PC机，基于Windows平台，专门负责测井数据的分析、显示、打印和存盘等。网络通信通过客户/服务器方式进行。下位机为客户机，上位机为服务器。

Abstract: The paper describes the system design of the special numerical control measure well system based on network SGX3 numerical control measure well system.The system is consisted of slave-computer and super-computer. Slave-computer and super-computer communicates by real-time network. slave-computer collecting the measure well data uses embedded PC(PC-104). Super-computer uses PC including windows system operation which analyses , show,print and store the measure well data.The network uses client/server mode. slave-computer is a client,and super-computer is a server.
