【摘要】 从生气母质、温压条件、构造作用和封盖条件四方面分析和总结了塔里木盆地凝析气藏的成藏条件。认为塔里木盆地的生气母质既有陆相腐殖型 ,又有海相腐泥型 ,但两种母质生凝析气的热演化阶段不一样。塔里木盆地凝析气藏富集温度为 70～ 130℃ ,压力范围为 35～ 6 0MPa。后期改造作用是生成次生凝析气藏的主要因素 ,良好的区域盖层又是凝析气藏富集的重要因素更多还原

【Abstract】 The conditions, in terms of hydrocarbon source, temperature, pressure, tectonic activities and sealing, for the formation of condensate gas pools in the Tarim basin are analyzed and discussed. It is concluded that the gas generating kerogens are of both the land derived humic type and the marine sapropelic type, withthe two types generating gas condensates at different thermal evolutional stages. The temperature and pressure ranges for the gas condensate accumulations in the basin are 70-130℃ and 35-60?MPa, respectively. The existence of favorable regional capping beds is an important factor for the enrichment of gas condensates, while later phase tectonic reworking is the major factor for the formation of secondary gas condensate pools.更多还原
