摘　　要：构造应力场的剧烈变化期与烃源岩排烃期、油气大规模运移期和聚集期具有较好的匹配性,盆地油气分布与其构造应力场之间存在着密切的关系。构造应力特别是成藏期构造应力对油气的运移、聚集和油气藏的形成起着重要作用,盆地构造应力场通过各种直接和间接的不同方式,影响甚至控制着油气的生成、运移和聚集。通过对柴达木盆地西部地区第三纪不同阶段的三维应力场数值动态模拟,分析该地区不同时期的应力场分布特点,结合已知的油气分布情况,认识应力场对油气分布的控制规律。There is a good comparability between the period of intensity alteration of stress field and the period of hydrocarbon release, migration and accumulation, and a consanguineous relation between the distribution of hydrocarbon and the stress field of a basin. The tectonic stress, especially the tectonic stress in the reservoir-formation stage in an oilfield, is of fundamental significance on hydrocarbon migration, accumulation and reservoir formation. The stress field of a basin controls the producing, migration and accumulation of hydrocarbon by some direct or indirect mode. Numerical simulation, especially the 3D dynamic simulation, is efficient for understanding the control of stress field on the hydrocarbon distribution.
