分组传送网（PTN）技术适应了IP业务快速发展带来的承载传输层的需求，PTN支持多种基于分组交换业务的双向点对点连接通道，具有适合各种粗细颗粒业务、端到端的组网能力，提供了更加适合于IP业务特性的“柔性”传输管道，具有完善的OAM机制，精确的故障定位和严格的业务隔离功能。 本文以环江油区数据传输网为研究对象，结合了数字化油田建设中办公系统、工业控制系统、VOIP、视频会议等各子系统对于传输承载系统的不同需求，对PTN技术在数字化油田的应用进行了研究和探讨。 通过调研和需求分析建立了环江油区的应用模型，对于模型细分了各个模块，对于各模块之间的关系和所涉及到的技术进行了系统性的研究，同时在研究结果的基础上提出了环江油区数据传输网的网络架构，并规划了设备的详细数据配置。 经过对实际网络的应用效果分析和测试，应用效果和测试结果均表明环江油区PTN数据传输网达到了预期的效果，满足了环江油区数字化油田建设的需求，同时本文针对目前系统存在的管理开销较大问题还提出了改进意见。 本文的研究结果证明了PTN技术是能够满足数字化油田数据传输需求的，这对于PTN技术在油田的推广应用具有重要参考意义。

Packet Transport Network (PTN) technology is adapt to the rapid development of IP services brought bearer transport layer needs, PTN supports a variety of packet-based bi-directional point-to- point channel, with the thickness of the particles for a variety of businesses, from end to end networking capability provide a more suitable IP service features "soft" transmission pipeline, with perfect OAM mechanisms, accurate fault location isolation and strict business. In this paper, HuanJiang Oilfield data transmission network for the study, combined with the construction of digital oilfield OA systems, Industrial control systems, VOIP, video conferencing and other different system needs of transport carrying for on PTN technology in digital oilfield were the study and discussion. Application of the model to establish HuanJiang Oilfield, for a breakdown of each module model, the relationship between the various modules and techniques involved in the systematic research, and proposed on the basis of research results through research and needs analysis HuanJiang oilfield network architecture oilfield data transmission network, and plan a detailed configuration data of the device. After the actual network application effect analysis and testing, apply effects, and test results show that the HuanJiang Oilfield PTN data bearer network to achieve the desired effect, to meet the needs of the construction of the HuanJiang Digital Oilfield, while this paper, the current system exists Management also raised the cost of a larger problem improvements. Results of this study prove that PTN technology is able to meet the needs of digital oil data transmission, which has important implications for PTN technology reference cited in the oilfield.
