摘　　要：通过对玉门老君庙油田M油藏 2 0多口井的生产数据进行统计分析和产能递减研究 ,以便为M油藏的合理开发、最优压裂、经济评价提供可靠的数据。结果表明 :M油藏在单采M3层时 ,压裂井产能递减规律呈直线递减 ;当合采M2 、M3 或合采M1、M2 、M3 层时 ,压裂井产能递减规律呈调和递减。Production data was statistically analyzed and productivity declining was studied for more than 20 wells in M reservoir of Laojunmiao oilfield, Yumen, in order to provide reliable data for reasonable development, optimal fracturing, and economic evaluation. The result showed that, in M reservoir, when layer M3 was produced alone, the productivity of fractured wells declined in straight line; when layer M2 and M3, or M1, M2 and M3 were commingled produced, the productivity declined harmonicly.
