【摘要】：近年来,随着信息科技的快速发展,为了进一步深化石油企业的信息化建设,石油公司在“十二五”规划中提出了油气生产物联网系统项目,以实现生产数据自动采集、远程监控、生产预警,支持油气生产过程管理,提高油气田生产决策的及时性和准确性,提高生产管理水平,降低运行成本和安全风险。油气生产物联网项目的实施离不开通信网络的建设,油气井分布范围广,需要实时上传的数据多,因此急需一套具有广覆盖、低时延、高带宽的通信网络系统。TD-LTE技术因其高速率、分组传送、低时延、广覆盖和向下兼容等技术优势,刚好满足油田行业用户对通信网络的需求,为当前因技术落后面临发展困境的包括石油行业在内的各行业领域通信网络建设提供了良好的契机。因此,本设计就是把TD-LTE技术引入油气生产物联网系统建设中,实现TD-LTE在油田环境中的网络规划设计。针对油气生产物联项目建设中通信技术不足的问题,建议了一套TD-LTE油田专网设计,本设计首先阐述了课题的研究背景及意义,分析了当前油气生产物联网建设中用到的主要几种无线通信技术,并对TD-LTE和Mc Wi LL进行了技术对比;然后介绍了TD-LTE系统的关键性技术,包括灵活的调度策略、ICIC及MIMO等;接着对油田的现有网络进行了分析,给出了TD-LTE网络规划的总体设计;在TD-LTE专网的详细设计中首先对公网和专网核心网EPC进行比较,对核心网进行了优化设计;频率组网部分是通过比较同频组网和异频组网的优缺点,并结合油田建网的实际情况,最终选择了同频组网;链路预算及覆盖分析部分首先考虑了业务允许的最大损耗,然后选择了一个与油田环境最相似的传播模型,给出具体的参数设置,最终得到小区的覆盖半径;系统吞吐量部分,首先对峰值吞吐量进行了分析,然后通过仿真得到了同频组网、20MHz带宽、8天线的上下行链路平均吞吐率。通过以上的分析和研究完成了TD-LTE的石油专网的规划设计。此设计所得到的数据已被应用到油气生产物联网项目的建设中,充分证明了此设计的可行性。
[Abstract]:In recent years, with the rapid development of information technology, in order to further deepen the informatization construction of oil and gas enterprises, the petroleum companies put forward the project of oil and gas production Internet of things system in the 12th Five-Year Plan, in order to realize the automatic collection of production data.Remote monitoring, production early warning, supporting oil and gas production process management, improving the timeliness and accuracy of oil and gas production decisions, improving production management level, reducing operating costs and safety risks.The implementation of the oil and gas production Internet of things project can not be separated from the construction of the communication network. The oil and gas wells are widely distributed and need more data to be uploaded in real time. Therefore, it is urgent to have a set of oil and gas wells with wide coverage and low delay.High-bandwidth communication network system .TD-LTE technology, due to its advantages of high speed, packet transmission, low delay, wide coverage and downward compatibility, can meet the needs of oil field users for communication networks.It provides a good opportunity for the construction of communication network in various fields, including petroleum industry, because of the technical backwardness.Therefore, this design is to introduce TD-LTE technology into the construction of oil and gas production Internet of things system, and to realize the network planning and design of TD-LTE in oil field environment.In order to solve the problem of insufficient communication technology in the construction of oil-gas production and material connection project, a set of special network design for TD-LTE oilfield is proposed. The research background and significance of the project are described in this design.This paper analyzes several main wireless communication technologies used in the construction of oil and gas production Internet of things, and compares the technology between TD-LTE and MC Wi LL, then introduces the key technologies of TD-LTE system, including flexible scheduling strategies, such as ICIC and MIMO, etc.Then the existing network of oil field is analyzed, and the overall design of TD-LTE network planning is given. In the detailed design of TD-LTE network, firstly, the EPC of public network and private network core network are compared, and the core network is optimized.In the part of frequency network, the advantages and disadvantages of the same frequency network and the different frequency network are compared, and combined with the actual situation of the oil field network, the same frequency network is finally selected.Then a propagation model which is most similar to the oil field environment is selected, and the specific parameters are set up, finally the coverage radius of the cell is obtained. In the system throughput part, the peak throughput is first analyzed.Then through simulation, the average throughput rate of the 20 MHz bandwidths and 8 antennas in the same frequency network is obtained.Through the above analysis and research completed the TD-LTE oil network planning and design.The data obtained from this design have been applied to the construction of the oil and gas production Internet of things project, which fully proves the feasibility of the design.
