摘　　要：关于惠民凹陷南坡中奥陶统海相海相碳酸盐岩的生烃能力,前人有不同的认识。文章应用国内对中奥陶统生烃能力的最新研究成果,结合塔里木盆地中奥陶统油气源的勘探实际,运用曲古1井有机质的丰度、类型和成熟度等生烃指标及中途测试、岩石脱气资料,对该区进行了较深入的分析。There exist different opinions about hydrocarbon generation capacity of the middle Ordovician carbonatite on the south slope of Huimin sag. Applying the latest research results in China and the actual exploration of middle Ordovician oilgas sources in the Tarim Basin, the author utilized hydrocarbon generating indexes including organic matter abundance, types, maturity etc. and the data of drillstem test and rock degassing of Qugu1 well for analysis deeply in this area. The research shows that this set of stratum has gas generation capacity instead of oil generation capacity.
