摘　　要：塔里木盆地油气勘探实践表明，不同类型圈闭的油气丰度差异较大，除了与圈闭的成藏条件有关外，在很大程度上还与圈闭的封闭样式及封闭效率有关，它们共同构成圈闭控油的重要因素。本文根据封闭要素及封闭面产状特征，建立了塔里木盆地７种封闭样式，进而讨论各种封闭样式对油气的封闭效率。Prospecting works have revealed that the hydrocarbon abundance is significantly different for various types of traps in Tarim basin. Depending on the conditions for trap formation, and on the sealing styles and efficiencies of traps to a great extent. These are important factors of traps within which hydrocarbons might accumulate. Authors suggest seven sealing styles based on the sealing factors and the occurrence of sealing surfaces, and discuss the sealing efficiency determined by the sealing nature for the various sealing styles in Tarim basin.
