摘要
中国某海上气田新建的无人驻守井口平台与中心平台之间无海底光缆敷设,平台之间需传输DCS生产数据和关断、语音、视频等信号。为建立安全、可靠的通信链路,采用4 G TD-LTE无线传输技术进行组网。4 G TD-LTE技术目前已广泛应用于陆地油田组网系统,技术和设备相对成熟,但在国内海上油气田尚未推广使用。通过比对单独敷设光缆和数字微波技术组网,4 G TD-LTE技术具有较好的价格优势与组网灵活性。经该海域某已建油田内部4G组网链路测试,得出4 G TD-LTE技术能够在海上建立稳定可靠的传输链路,满足油气田生产需要。
There's no submarine fiber optical cable between the newly built unmanned wellhead platforms and the central platform in certain China offshore gas field,while signals such as DCS production data,wellhead shutdown,video and voice need to be transmitted between the platforms.To solve the problem,a 4G TD-LTE wireless transmission technology is utilized to build a safe and reliable communication link.The 4G TD-LTE has been widely used in onshore oil field network,with mature technology and equipment available in the market.However,it has not been promoted in the domestic offshore oil and gas fields.By comparing with the fiber optic cable and digital microwave technology,4G TD-LTE technology has proved its price advantage and network flexibility.An in-house 4G network link test has been conducted in certain China offshore oil field,which demonstrates that 4G TD-LTE technology can build a stable and reliable offshore transmission link to meet the production.
