水合物浆体流动规律研究进展

摘要

With the development of natural gas into deeper sea, the oil-gas pipeline plugging problems caused by gas hydrate has been paid more attention. Hydrate slurry technology is a new technology on security of deep water flow, and large-scale industrial application of pipeline transportation technology in submarine is based on the research on the flow characteristics of hydrate slurry. The status and progress in research of hydrate slurry flow law were reviewed with the emphasis on the rheological behavior and pressure drop of hydrate slurry. The directions of future researches were pointed and some suggestions were given.%随着海洋天然气开发深度的增加,混输管线的天然气水合物堵塞问题越来越受到重视,水合物浆液流动技术是深水流动保障技术的新工艺,而研究水合物浆液的流动特性是实现海底管输技术大规模工业应用的重要基础.综述了水合物浆体流动规律的研究现状和进展,主要从水合物浆体的流变性和压降规律等方面对国内外水合物浆体流动规律的研究进展进行了归纳,指出了水合物浆体研究方向并给出了建议.
