摘要:
采用理论分析和数值计算相结合，进行了引射装置设计，并以牙哈气田为例，探讨了引射装置用于天然气田轻烃回收工艺时存在的优势，得出主要结果和结论如下：1) 本文建立的引射装置数值计算模型能够得到装置内部流场信息，可用于装置结构的优化；2) 喷嘴可调引射器结构，可提高装置工况适用性，可实现不同流量的调节；3) 引射技术能够利用高压天然气自身压力能引射低压流体，大幅度减小凝析气田轻烃回收装置的能耗，为天然气集输处理提供一个新途径。
The method of theoretical analysis combining with numerical calculation in this paper has been adopted to design ejector device, and the YaHa oil-gas field has been cited as an example to discuss the advantages of ejector device used in the process of light hydrocarbon recovery from condensate field. The main results and conclusions are as follows: 1) The established numerical model of ejector machine can get the information of internal flow inside the device, so it could be used in the optimization of device structure; 2) The adjustable nozzle of ejector structure can improve the appli- cability of operational condition and realize regulation for different flow rate; 3) The ejector technology can utilize the high pressure gas with high pressure energy itself to inject the low pressure fluid and greatly reduce the energy consump- tion of light hydrocarbon recovery, providing a new way for natural gas gathering and transferring process.
