摘　　要：油气聚集系数是油气资源评价中最为关键的参数之一。从苏北盆地的实际情况出发,统计分析30多年来的勘探成果和探井成功率,应用概率中值法和探井网格统计法,结合地质综合研究选取聚集系数,并应用于油气资源评价。苏北盆地主要构造单元的油气聚集系数集中在35%～43%之间。该成果为油气资源评价提供了更为客观参数,对地质条件相似地区的油气聚集系数研究和选取具有参考意义。The coefficient of hydrocarbon accumulation was one of the key parameters for hydrocarbon resource evaluation. The exploration data of over 30 years were analyzed in Subei Basin,hydrocarbon accumulation coefficient was determined by statistical methods, which was primarily integrated with the probability value of well success rate and well grid. The main tectonic units of hydrocarbon accumulation coefficient were ranged from 35% to 43%. The results provide more objective parameters for the oil and gas resource evaluation,and reference for similar regions under the petroleum geological conditions.
