摘要
塔里木盆地凝析气分布广泛，成因复杂，以富、特富凝析气藏为主，具有很高的经济价值。盆地中存在陆相腐殖型气源岩和海相腐泥型气源岩，它们在不同演化阶段生成多种组分、不同温压状态的凝析气，在运移、聚集和成藏过程中，烃体系分异、富化，多期成藏，多个烃体系混合，形成初始型、分（馏）析（出）变异型和富化变异型这３类凝析气藏。
Condensate gas of complex origin is widely distributed in Tarim basin of China, which is dominated by rich and very rich condensate gas pools and so has a very high economic value. The continental humic gas source rock and marine sapropelic gas source rock are both developed in the basin, which generated at different evolution stages multi-component condensate gases with different temperatures and pressures. During migration, accumulation and pool formation of gas, three types of rudiment, fraction-variation and enrichment-variation condensate gas pool are formed due to the segregation, enrichment, multistage pool formation and mixture of hydrocarbon systems.
