【摘要】：近年來,隨著信息科技的快速發(fā)展,為了進(jìn)一步深化石油企業(yè)的信息化建設(shè),石油公司在“十二五”規(guī)劃中提出了油氣生產(chǎn)物聯(lián)網(wǎng)系統(tǒng)項(xiàng)目,以實(shí)現(xiàn)生產(chǎn)數(shù)據(jù)自動(dòng)采集、遠(yuǎn)程監(jiān)控、生產(chǎn)預(yù)警,支持油氣生產(chǎn)過程管理,提高油氣田生產(chǎn)決策的及時(shí)性和準(zhǔn)確性,提高生產(chǎn)管理水平,降低運(yùn)行成本和安全風(fēng)險(xiǎn)。油氣生產(chǎn)物聯(lián)網(wǎng)項(xiàng)目的實(shí)施離不開通信網(wǎng)絡(luò)的建設(shè),油氣井分布范圍廣,需要實(shí)時(shí)上傳的數(shù)據(jù)多,因此急需一套具有廣覆蓋、低時(shí)延、高帶寬的通信網(wǎng)絡(luò)系統(tǒng)。TD-LTE技術(shù)因其高速率、分組傳送、低時(shí)延、廣覆蓋和向下兼容等技術(shù)優(yōu)勢,剛好滿足油田行業(yè)用戶對通信網(wǎng)絡(luò)的需求,為當(dāng)前因技術(shù)落后面臨發(fā)展困境的包括石油行業(yè)在內(nèi)的各行業(yè)領(lǐng)域通信網(wǎng)絡(luò)建設(shè)提供了良好的契機(jī)。因此,本設(shè)計(jì)就是把TD-LTE技術(shù)引入油氣生產(chǎn)物聯(lián)網(wǎng)系統(tǒng)建設(shè)中,實(shí)現(xiàn)TD-LTE在油田環(huán)境中的網(wǎng)絡(luò)規(guī)劃設(shè)計(jì)。針對油氣生產(chǎn)物聯(lián)項(xiàng)目建設(shè)中通信技術(shù)不足的問題,建議了一套TD-LTE油田專網(wǎng)設(shè)計(jì),本設(shè)計(jì)首先闡述了課題的研究背景及意義,分析了當(dāng)前油氣生產(chǎn)物聯(lián)網(wǎng)建設(shè)中用到的主要幾種無線通信技術(shù),并對TD-LTE和Mc Wi LL進(jìn)行了技術(shù)對比;然后介紹了TD-LTE系統(tǒng)的關(guān)鍵性技術(shù),包括靈活的調(diào)度策略、ICIC及MIMO等;接著對油田的現(xiàn)有網(wǎng)絡(luò)進(jìn)行了分析,給出了TD-LTE網(wǎng)絡(luò)規(guī)劃的總體設(shè)計(jì);在TD-LTE專網(wǎng)的詳細(xì)設(shè)計(jì)中首先對公網(wǎng)和專網(wǎng)核心網(wǎng)EPC進(jìn)行比較,對核心網(wǎng)進(jìn)行了優(yōu)化設(shè)計(jì);頻率組網(wǎng)部分是通過比較同頻組網(wǎng)和異頻組網(wǎng)的優(yōu)缺點(diǎn),并結(jié)合油田建網(wǎng)的實(shí)際情況,最終選擇了同頻組網(wǎng);鏈路預(yù)算及覆蓋分析部分首先考慮了業(yè)務(wù)允許的最大損耗,然后選擇了一個(gè)與油田環(huán)境最相似的傳播模型,給出具體的參數(shù)設(shè)置,最終得到小區(qū)的覆蓋半徑;系統(tǒng)吞吐量部分,首先對峰值吞吐量進(jìn)行了分析,然后通過仿真得到了同頻組網(wǎng)、20MHz帶寬、8天線的上下行鏈路平均吞吐率。通過以上的分析和研究完成了TD-LTE的石油專網(wǎng)的規(guī)劃設(shè)計(jì)。此設(shè)計(jì)所得到的數(shù)據(jù)已被應(yīng)用到油氣生產(chǎn)物聯(lián)網(wǎng)項(xiàng)目的建設(shè)中,充分證明了此設(shè)計(jì)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.
