摘　　要：通过对构造应力场与低渗透储层中裂缝分布、油气运移和聚集以及断层纵向封闭性之间关系的分析，说明根据构造应力场的分布，不仅可以定量预测裂缝性油气藏的分布规律以及油气的运移方向与聚集场所，而且还可定量评价断层的封闭性。因此，从构造应力场的角度对油气的分布进行评价和预测，将对隐蔽性油气藏的勘探具有指导作用。Tectonic stress is main power in the process of oil and gas forming, it has extremly great influence on the formation, migration, accumulation and storage of oil and gas. From analysing the relationship between tectonic stress field and low permeable reservoir, migration and accumulation of oil and gas and fault sealing, the authors think that not only the distribution of fractured reservoir, migration and accumulation of oil and gas can be predicted, but also the fault sealing can be evaluated quantitatively by studying tectonic stress field. So, in the study of oil and gas system, the method of evaluation and prediction of oil and gas distribution from tectonic stress field has great guide to prospect hidden oil and gas pool.
