摘　　要： 随着自动控制、网络和计算机技术的不断发展,通过网络实现随钻测井系统/(LWD/)数据的远程传输,已经在国内外石油行业成为研究热点。目前在工业数据传输领域大多采用有线的通信方式进行,虽然经济实用,但在很大程度上限制了应用场合的拓展。为了使远距离数据传输实现得更灵活方便,本文选用GPRS技术进行远程数据的传输。本文致力于基于GPRS的LWD数据远程传输系统的研究。该系统是传统计算机技术、现代计算机网络技术和GPRS移动网络技术的结合,具有功能丰富、便于操作、成本较低、安装维护方便、实时性好、可靠性高、运营费用低,易于二次开发和扩展等特点。 本文通过分析远程监测系统的国内外研究现状,对当前各种监控系统的监控方式进行分析和比较,并结合传统远程监控系统模型,提出了基于GPRS的LWD数据远程传输系统的系统方案。通过比较目前应用的数据传输方式,提出了实现远程数据传输的技术方案,详细阐述了的GPRS体系结构和GPRS网络特性,设计了基于的数据传输系统的方案。主要包括系统的组网方案、通信方案的选择、各组成部分的功能和采用APN技术保证了数据传输的可靠性和安全性。 本文详细分析和设计了基于GPRS的LWD数据远程传输系统的方案。重点介绍了系统结构、组成和工作过程,并对各系统组成部分的功能和设计进行详细的说明。然后对客户端和服务器端的软件设计流程作了详细的说明和介绍,并对各功能模块和数据库进行了详尽的设计说明。最后对基于GPRS的LWD数据远程传输系统开发流程进行了总结。 With rapid development of automatic control and network techniques, network-based LWD Data Remote Transmission is becoming an investigating hotspot in the oil industry. At present, the way of wired communication to transmit data has been mostly used in the field of industry, though very economical and practical, wired data transmission has limited its application prospects to a large extent. In order to make the remote transmission more flexible and convenient, in this paper, GPRS technology has been selected to transmit the remote data. This thesis is researching on the system of LWD Data Remote Transmission, based on GPRS, integrates of traditional computer, modern Internet and GPRS technology. It has many merits, such a multiple functions, low cost, well real time capability and high reliability. It is also convenient to operate, easy to install, maintain and upgrade. After analyzing present researches and comparing the current means on remote wireless monitoring systems of elevators, integrating traditional modal of remote monitoring system, we advance LWD Data Remote Transmission System based on GPRS .Through compared the present ways of the wireless data transmission, GPRS has been chose as to transmit the remote data. Firstly, explaining the GPRS in detail, including its system frame and its network feature. Then, designing the data communication system, mainly analyzing the form-net project and the communication scheme of the system and the function of the constitution, besides, analyzing the system’s security . This thesis designs and develops the scheme of LWD Data Long-rang Transmission System Based on GPRS in detail, emphases on system structure, system constitutes and system work process, and also explains the system constitutes’function and design details. Then it narrates the design of software process to client and center monitor, and introduces the detail of function module development and database design. Finally, the development flow of LWD Data Long-rang Transmission System Based on GPRS was summarized.
