气举采油工艺是辽河牛居油田增产的主要措施,近年来又围绕降低注入气液比、提高气举井经济效益开展了现场试验其具体作法是:加强注入气的净化、严格控制注气压力、降低气举井井口油压、低产井开展间歇气举试验,推广可投捞式偏心气举管柱、井口安装高压水套加热炉。 The gas lift method is the main measure to increase the production of the Liaohe Niuju oilfield. In recent years, the field trial has been carried out to reduce the gas-liquid ratio of injection and improve the economic benefit of the gas well. The specific practices are as follows: to strengthen the purification of injected gas and strictly control the gas injection pressure , Reducing gas lift wellhead hydraulic pressure, low production wells to carry out intermittent gas lift test to promote the fishing can eccentric gas column, wellhead installation of high pressure water jacket furnace.
