摘要：塔里木盆地台盆区寒武系已发现的碳酸盐岩潜山油气藏显示了巨大的勘探潜力，然而由于塔里木盆地经历了多期的构造运动，早期形成的寒武系碳酸盐岩油气藏经历了后期的调整、改造、破坏和再聚集，油气成藏过程复杂，已有的油气成藏理论难以指导该地区的油气勘探。目前寒武系地层钻探成功率偏低，仅为25%。从地质角度出发，采用“功能要素匹配－构造过程叠合一晚期相势源复合的新方法对塔里木盆地寒武系失利井原因进行分析，试图揭示该地区油气成藏机理，以便有效地指导油气勘探。通过对塔里木盆地寒武系的15口失利井的分析结果表明：80%的失利井由于功能要素不匹配，落在有利成藏领域之外而失利；7%的失利井由于构造过程叠合改造破坏了早期形成的油气藏，落在有利勘探区带之外而失利；13%的失利井由于晚期相-势－源不复合，落在有利勘探目标外而失利。该方法完美地解释了塔里木盆地寒武系钻探失利的原因，说明其在指导油气勘探中的可行性和有效性，对以后的油气勘探具有重大的现实意义。

Abstract : The proved carbonate hydrocarbon reservoirs in burial hills of Cambrian have shown the huge explora tion potential; however, because the basin has gone through multiple structural events, the reservoirs formed previously in Cambrian were affected by later structural events, and they were adjusted, transformed, destroyed and reformed. The complexity of the superimposed basin leads to a loss to present theories. At present, the suc-cess ratio of exploration about 25% in Cambrian is low. This paper discusses the failure reasons of these 15 holes from the geological process of hydrocarbon enrichment by the methods of "functional elements matching, struc-tural process superimposing and facies-potential-sources coupling at late stage", and tries to bring to light the hydrocarbon accumulation mechanism to improve the efficiency of exploration. The results turns out that, 80 percent of abortive holes locating out of the promising accumulation districts failed because they did not match functional factors ; 7 percent of them locating out of promising exploration areas failed because the previous res ervoirs were destroyed in the later structural events; 13 percent of them failed because they did not meet the fa
