摘　　要：明确海上油气开发生产"一体化运营"模式下通讯需求的典型应用场景,对海上作业设施的工作环境特点和通信需求及难点进行分析,比较了目前海上油气田常用的卫星、光纤、常规微波技术等几种通信技术的特点。为满足海上通信高可靠性、高可用性、高带宽、远距离等要求,提出基于Ceragon公司的PointLink海洋级微波通信系统为解决方案。该方案采用混合频率和四分集技术,克服海洋环境中通讯多径衰落的影响;创新的天线基于蛮力算法,即使在高振动环境下也能提供可靠的跟踪记录;通过补偿算法,与旋转设施通信时也可以实现无缝切换,确保通信360°准确无误连续连接。满足海上设施通信的带宽、可靠性、可用性和成本要求。Clarifying typical application scenarios of communication demand under the integrated operation mode of offshore oil and gas development and production,the working environment characteristics,communication requirements and difficulties of offshore operation facilities were analyzed.The characteristics of several communication technologies such as satellite,optical fiber and conventional microwave technology used in offshore oil and gas fields were compared.In order to meet the requirements of reliability,availability,bandwidth and distance of offshore communication,a new offshore microwave communication system based on Ceragon′s PointLink was created.The hybrid frequency and QUAD diversity technology were adopted to overcome the influence of multipath fading in marine environment.The innovative antenna was based on brute force algorithm,which can provide reliable tracking records even in high vibration environment.Through the compensation algorithm,it can also achieve seamless switching when communicating with the rotating facilities to ensure 360°accurate and continuous connection.It can meet the requirements of bandwidth,reliability,availability and cost of communication for offshore facilities.
