分析了天然气脱硫、脱水、脱碳、脱汞及凝液回收等预处理工艺对边远分散井的适应性，同时对阶式制冷循环、混合冷剂（M RC ）制冷循环和膨胀机制冷循环3种天然气液化工艺应用于边远分散井的工作特性进行了对比。阶式制冷由于工艺复杂不适用于边远分散井。M RC制冷操作弹性大、能耗低、适应性较强，可在大多数边远分散井应用。膨胀机制冷操作简单、占地面积小且易橇装化，适合在工况较为稳定且有较高井口压力的场合应用。从当前的技术水平来看，不含硫、低含碳且重烃含量低的单井更适合进行LNG液化工艺的应用和推广。
分析瞭天然氣脫硫、脫水、脫碳、脫汞及凝液迴收等預處理工藝對邊遠分散井的適應性，同時對階式製冷循環、混閤冷劑（M RC ）製冷循環和膨脹機製冷循環3種天然氣液化工藝應用于邊遠分散井的工作特性進行瞭對比。階式製冷由于工藝複雜不適用于邊遠分散井。M RC製冷操作彈性大、能耗低、適應性較彊，可在大多數邊遠分散井應用。膨脹機製冷操作簡單、佔地麵積小且易橇裝化，適閤在工況較為穩定且有較高井口壓力的場閤應用。從噹前的技術水平來看，不含硫、低含碳且重烴含量低的單井更適閤進行LNG液化工藝的應用和推廣。

Adaptability of natural gas pretreatment process including desulfurization ,dehydra-tion ,decarburization ,demercuration and condensate recovery in outlying dispersed well are ana-lyzed .In order to be used in outlying dispersed well ,working characteristics of three natural gas liquefaction processes including cascade refrigeration cycle ,mixed refrigerant refrigeration cycle and expander refrigeration cycle have also been compared .The process of cascade refrigeration cycle is too complex to be suitable for outlying dispersed well .MRC refrigeration has high flexi-bility ,low energy consumption and strong adaptability ,therefore it can be used to most of outly-ing dispersed wells .Expander refrigeration is characterized by simple operation ,small occupied area and easy to be skid-mounted ,so it is suitable for stable operation conditions and higher well head pressure .So far as current technology level ,the single wells containing no sulfur ,low car-bon dioxide and low heavy hydrocarbon content are more suitable for outlying dispersed well .
