A lot of domestic gas fields have been continuously developed for many years and most of the gas wells have entered the stage of pressure drop and lower production. The ex-isting gathering and transportation facilities and technology will not be able to meet the needs of the development of gas fields in the future.It is needed to carry on the study on the timing and mode of boosting for the gas fields in advance in order to get maximum benefit of the gas fields. Based on the historical data of the production wells of a gas field in China, this paper predicted the output and pressure changes of each well and in the condition of the maximum utilization of the existing facilities, through the hydraulic calculation, simulated the required minimum wellhead pressure to maintain normal production in different years.Then the boost timing and mode of the gas field will be determined by the amount and yield of gas wells that can be normally produced without the measures and the increased yield by taking measures.%国内很多气田已经连续开发多年,大部分气井已经进入降压、降产的开发阶段,已建的集输设施及工艺将不能满足气田未来的开发需要,需提前对气田的增压时机及增压模式进行研究,以保障气田效益的最大化.在调研国内某气田各生产井历史数据的基础上,预测各井的产量、压力变化,在最大限度利用现有设施的条件下,通过水力计算,模拟气井不同年份正常生产需要的最低井口压力,确定不采取措施时能正常生产的气井数量及产量,和采取措施后增加的天然气产量,从而确定气田的增压时机和增压模式.
