我国凝析气藏主要分布在渤海湾、塔里木、吐哈等盆地及东、南沿海陆架区。凝析气总储量约４０００×１０８ｍ３，占天然气总储量的三分之一。气藏主要形成于陆源母质成烃体系和煤成烃体系，湖相和海相腐泥型成烃体系形成的此类气藏很少。腐殖型或偏腐殖型源岩是凝析气藏富集的内在因素，除常规气藏要求的地质条件外，温压条件必不可少，该类气藏富集的温度为７０～１３０℃，压力为３０～６０ＭＰａ。综合分析认为新疆三大盆地、东北－内蒙裂谷系和东部裂陷盆地及南海、东海、渤海湾等地为凝析气藏的重点勘探地区。
Condensate gas reservoirs in China are mainly distributed in the Bohai Bay, Tarim, Tuha Basins and the east and south coastal shelf areas. Total condensate gas reserves of about 4000 × 108m3, accounting for one third of the total reserves of natural gas. The gas reservoirs are mainly formed in the terrigenous parent hydrocarbon-forming systems and coal-forming systems. There are only a few such gas reservoirs formed in the lacustrine and marine sapropelic hydrocarbon-forming systems. Humic or humus source rock is the intrinsic factor of enrichment of condensate gas reservoirs. In addition to the geological conditions required by conventional gas reservoirs, temperature and pressure conditions are essential. The enrichment temperature of such gas reservoirs ranges from 70 to 130 ℃, the pressure is 30 ~ 60MPa. The comprehensive analysis shows that the three major basins in Xinjiang, the northeast-Inner Mongolia rift valley and the eastern rift basin and the South China Sea, the East China Sea and the Bohai Bay are the key exploration areas for condensate gas reservoirs.
