摘　　要：成岩圈闭在阿姆河右岸西区广泛发育,具有气水关系复杂、一井一藏的特征。通过研究成岩圈闭的成因,深化了成岩圈闭的概念,探讨了成岩圈闭的勘探方法。针对阿姆河右岸西区成岩圈闭分布广泛、成因复杂、勘探潜力大的特性,利用古构造恢复技术、复杂碳酸盐岩储层预测技术,研究了阿姆河右岸西区成岩圈闭的特点,总结了在成岩圈闭勘探中的认识,得出后期成岩作用和新构造运动是形成成岩圈闭的两大关键因素,所形成的成岩圈闭具有气水关系复杂、气水界面倾斜、一井一藏的特征。阿姆河右岸西区成岩圈闭的勘探实践得出,以研究古构造为出发点,利用岩芯资料,结合储层预测研究成岩作用和储层发育,是勘探成岩圈闭的有效方法。Lithogeny trap with complex relationship between gas and water is developed widely in the west area of Amu- Darya Basin. Some lithogeny traps are characterized by very complex water-gas relationship with different reservoir for each single well. The article emphasizes the concept of lithogeny trap and analyzes the exploration methods on lithogeny trap by learning the causes of lithogeny traps. Based on exploration practice in west area of Amu-Darya Basin, and taking advantage of paleostrucmre recovering and complex carbonate reservoir prediction technology, we researched the characters of lithogeny trap which conclude the recognition of lithogeny trap. Later stage lithogeny function and new tectonic movement are both key factors in the formation of lithogeny traps with complex water-gas relationship, inclined gas-water contact, and different reservoir for each single well. The exploration practices in west area of Amu-Darya Basin lead to following conclusions ： the palaeostructure learning, which is followed by the research on lithogeny and reservoir development on the basis of cores and reservoir prediction is effective method in lithogeny trap exploration.
