摘要： 深海油气田低温高压的环境特点，使海底管线水合物堵塞现象日益严重。针对上述油气田出现的流动安全保障问题，依托中海石油深水天然气珠海高栏终端，建立海上油气田流动安全中试评价基地—大型海底混输管道多相流水合物实验环道，逐步突破制约海上油气田安全开发和运行的流动安全技术瓶颈，为保障我国海上油气田的安全运行提供技术手段和技术支撑。该装置属于高压、实液的大口径水合物实验系统，总长350 m，内径约150 mm，设计压力为21 MPa，并以实液为实验介质。本环道可用于低温、高压条件下油气水多相流流动规律、水合物生成、水合物防控技术等实验研究，并且可进行不同种类水合物抑制剂、相关仪表、设备性能的检测与评价。

Abstract: Hydrate blocking phenomenon in subsea pipelines is becoming more and more serious due to the environmental characteristics of low temperature and high pressure in deep⁃water oil and gas fields. In response to the above problems of flow assurance in the deep sea oil and gas field, relying on the Zhuhai Gaolan terminal of CNOOC deepwater natural gas, a multi⁃phase hydrate experimental loop of large⁃scale subsea mixed transportation pipeline was established in the pilot evaluation base of offshore oil and gas field flow safety, which could break through the technical bottleneck of flow assurance that restricts the safe development and operation of offshore oil and gas fields, and provide technical means and support to ensure the safe operation of offshore oil and gas fields in China. The total length of this loop is 350 m, the inner diameter is about 150 mm, and the design pressure is 21 MPa. This device belongs to a high⁃pressure, large⁃caliber hydrate experimental system with crude oil as experimental medium. In this paper, this loop could be used for experimental study on the principle of oil⁃gas⁃water multiphase flow, hydrate formation and hydrate control technology under low temperature and high pressure conditions. It could also be used to screen and evaluate the performance of various hydrate inhibitors, related instruments and equipment.

Key words: Measuring instrument, Multiphase flow loop, Hydrate, High pressure
