The Design And Implementation Of Well Site Data Processing And Network Transmission System

The development of the remote data transmission technology provides a critical condition for the realization of well site operations information. A data processing and transmission system is designed to solve the problem of dispersive distribution and poor environment of the well site. So quick, efficient and stable data transmission between the well site data center and the field system is achieved and the working field can be monitored in real time. In order to improve the efficiency and security of data transmission, the data is compressed and encrypted before transmission.Firstly, the paper analyzes main problems of well site operation and network communication. Then a solution based on data encryption, data compression and reliable data transmission technology is proposed. The system consists of two main parts, the field system and the base system, which runs on different hardware devices. In order to realize the communication between the field and the base systems, the paper makes full use of the inherent TCP/IP protocol. And some user-defined communication protocols are designed in the system. With methods of Windows Socket program design and implementation, the communication between different hardware devices is designed and implemented.In the system architecture, the system components and software architecture framework are expatiated. The function of each module and the entire system architecture model are described. Then system working processes, programming procedures and technical essential of client/server communication mode is analyzed.According to the structure of the system, every steps of technical application are considered deeply. Then a method which can handle the data for fault-tolerant processing based on well site information transfer specification datasheet is proposed. The system adopts the DES encryption algorithm to solve the security problem of the data transmission. This algorithm, based on the combination of confusion and diffusion, has very high complexity, so it can enhance the system's security. Meanwhile, since using LZW algorithm, the system transfers data smoothly and in real-time. In addition, the system has data storage and resend function to prevent data loss caused by network failures. Therefore, the system realizes the reliability of data transmission. Finally, in the view of overall system architecture and the implementation of the data processing and transmission, the paper deals with the realization of the field system and the base system in detail. The research results and technical features of the system are listed in the end of the paper.
