摘　　要：通过对高邮凹陷北斜坡中部沙埝地区沙50A井泰二段暗色泥岩系统取样，详细评价了其有机质丰度、类型、成熟度等各项指标，并依据泰州组烃源岩评价结果和成熟门限深度值划定了高邮凹陷泰州组有效烃源岩的分布范围，计算了相应的资源量。结果表明，该区泰州组有效烃源岩主要分布于泰二段底部“六尖峰”泥灰岩段，该段有机质丰度较高，类型较好，具有较好生油能力；该区泰二段烃源岩已处于成熟阶段，对应门限深度为2550m；有效烃源岩集中分布于高邮凹陷北斜坡中东部地区，生油量为2．9×10^8t，占高邮凹陷总生油量的60％，具有较大的勘探潜力。By systematic sampling the Dark Mudstone of the 2nd member of Taizhou Formation,the S50A well in the central North Slope of Gaoyou depression, its organic matter abundance, type, maturity and other indicators were detailed evaluatd. The results show that the district Taizhou effective source rocks are mainly distributed in the bottom of the ＂six peak＂ of 2nd member of Taizhou Formation;the maturity threshold were the depth of 2550 meters; Effective hydrocarbon source rocks distributed Jn the northern slope of Gaoyou Depression eastern region, and oil production to 2.9× 10^8t, oil accounted for Gaoyou sag 60% of the total students, with great exploration potential.
