摘　　要：针对采用井下节流装置的A井开展地面工艺适应性评价试验。通过采取停运采气管道电热带、调节天然气换热量的方法,监测地面工艺管道的运行压力、运行温度、冻堵时间等参数,研究各项参数与水合物的生成关系。A井应用井下节流装置后的采气管道运行压力、电伴热功率和加热炉功率明显降低,地面工艺优化空间大。徐深气田推广井下节流工艺,可有效降低地面工艺建设投资,减少能源消耗和药剂使用,有助于提高气田开发经济效益。This paper researches into adaptability evaluation test of surface engineering for downhole throttling technology applied in A well.Some influential factors that influence the generation of hydrate have been determined by stopping ribbon heater and adjusting heating furnace. The operating pressure, operating temperature and freeze- blockage time were monitored.Research has shown that the operating pressure of pipeline was decreased.There is a relatively large optimization space of ribbon heater and heating furnace power.Both electric energy and the medicaments have been saved. The downhole throttling technology can save many investments on surface engineering,and increase the economic benefit.
