塔里木盆地油气勘探与油气再次运移

HYDROCARBON EXPLORATION AND REMIGRATION IN TARIM BASIN

塔里木盆地的油气勘探工作所取得的成果，无论从哪个角度看都是十分巨大的。但目前在石油地质理论指导勘探实践方面遇到了难题，曾指导我国东部油气勘探取得成功的理论，在这里基本失效。在探索寻找和总结新理论的过程中，发现近年来所论证的油气再次运移的理论是油气藏形成三环节（油气生成、油气运移、油气聚集）的中心环节，它反映了中国多旋回构造演化的特点，符合油气流体矿产富集的规律，所以，它应该成为目前解决塔里木盆地油气勘探难题的钥匙。

Rich results in hydrocarbon exploration have been obtained in Tarim basin, while the difficulties in petroleum geology theory guiding exploration practice are encountered at present. Successful oil/gas exploration theories in eastern China failed in Tarim basin. During development of new theory, oil and gas remigration theory demonstrated by the author in recent years played a central role in reservoir formation(including oil/gas generation, migration and accumulation). It reflected the characteristics of polycyclic tectonic evolution in China, accorded with enrichment of fluid mineral product such as oil and gas.Therefore it is a key to solving hydrocarbon exploration difficulty in Tarim basin at present.
