摘要:

通过对柴达木盆地油气成藏地质条件及成藏过程的系统研究,柴达木盆地油气藏形成主要受到6种因素的控制:(1)生烃凹陷控制油气总体分布格局;(2)储集层质量影响油气藏的形成;(3)异常流体动力场控制油气的运移和聚集;(4)油源断层控制油气藏的形成;(5)喜山运动中晚期活动控制构造圈闭的形成和发展;(6)圈闭带的分布决定油气藏的具体分布。

Abstract:

Systematic study of the geological conditions and processes of hydrocarbon accumulations in Qaidam basin shows that there were six main factors controlling hydrocarbon accumulations. (1) Hydrocarbon generating sag controlled the distribution pattern of oil and gas. (2) Reservoir quality influenced the formation of oil and gas reservoirs. (3) Abnormal hydrodynamic field controlled the migration and accumulation of hydrocarbons. (4) Faults in source rocks controlled the formation of oil and gas reservoirs. (5) Middle and late Himalayan movements determined the formation and development of structural traps. (6) Occurrence of trap belts determined the specific distribution of pools.

Key words: Qaidam basin, hydrocarbon accumulation, main control factor
