摘　　要：随着深海油气资源的逐渐开发,传统天然气水合物防治方法的局限性越来越明显,低剂量天然气水合物抑制剂(LDHI)的使用逐渐受到关注和重视,管道天然气水合物的抑制策略也正在发生转变。为此,介绍了国内外天然气水合物抑制技术的最新进展,分析了目前采用热力学抑制剂完全抑制天然气水合物策略的局限性,结合笔者自己的研究成果,整合提出了管道天然气水合物的风险管理对策,即允许管道中形成天然气水合物,通过对天然气水合物流体的控制来实现油气管道的安全畅通运行。分析比较后指出:风险管理抑制策略必将成为管道天然气水合物的主要抑制策略,将有可能为石油天然气工业带来巨大的经济效益。With the development of deepwater hydrocarbon resources,the limitations of traditional natural gas hydrate control methods have been brought out.The low-dosage hydrate inhibitor(LDHI)is gradually being highly concerned and the concept of gas hydrate inhibiting policy for the pipelines is also changing.Therefore,this paper first introduces the latest progresses in gas hydrate inhibitor techniques,then analyzes the limitations of the present thermodynamic inhibitors,and finally puts forward the gas hydrate inhibiting policy based on risk management for the pipelines,namely the formation of gas hydrate will be allowed in the pipeline and the safe and smooth operation of the oil and gas pipeline will be achieved through control of the gas hydrate fluid.The results show that the hydrate inhibiting policy based on risk management will definitely become the main gas hydrate controlling strategy for the pipelines and will bring huge economic benefits for the oil and gas industry.
