基于FLUENT的含砂气体在压缩机内流场模拟与研究

The Compressor of Flow Field Simulation and Research with Sand Gas based on FLUENT

随着气田的开采,进口压力逐渐降低,气井的出沙现象也越来越严重。在天然气增压过程中,砂粒的存在会使压缩机内积垢严重,缸体磨损厉害、压缩机管道振动较大,现场噪声大,严重阻碍了生产机组安全运行。以西北某气田含砂气质为研究对象,建立压缩机流场模型,对不同粒径的砂粒在压缩机内的流场运动进行研究,分析了不同粒径不同砂含量和不同进气温度下的残留率,为保证压缩机高效安全运行,使低压气井得到有效开发提供条件。

With the field of mining, inlet pressure decreases, gas wells and growing phenomenon of sand. In the natural gas pressurization process, the presence of sand inside the compressor fouling serious, cylinder wear badly, compressor pipe vibration is large, on-site noise, a serious impediment to the safe operation of the production unit. A gas field in northwest sand temperament as the research object, the establishment of the compressor flow model for different size of sand grains in the compressor flow field motion studies to analyze the content of the different size and different sand under different inlet temperature residual rate, in order to ensure efficient and safe operation of the compressor, the low-pressure gas wells provide the conditions for effective development..
