【摘要】 天然气水合物形成后堵塞井筒、管线、阀门及各种设备,给天然气的开采、集输和加工带来危害,如何经济有效地防止水合物生成是很多油气田面临的问题。大牛地气田产水气井在不同程度上存在水合物问题,某些气井水合物堵塞相当严重。本文分析了大牛地气田水合物形成情况和水合物抑制剂的使用情况,通过现场数据对甲醇和乙二醇进行对比,优选甲醇作为大牛地水合物抑制剂,并给出合理的抑制剂用量为现场应用提供了理论指导。更多还原

【Abstract】 Gas hydrate plugs wellbore,pipeline,valve and other equipments and cause danger or serious accident in exploitation,transportation and machining.How to prevent gas hydrate in efficient and effective way is still problem many oil and gas fields have to face.This problem also persecutes production of DaNiu gas field.By analyzing gas hydrate formation condition and servicing condition of inhibitor,collates methanol and glycol by locale data,chooses methanol to prevent gas hydrate and gain reasonable calculation to guide local application.更多还原
