摘要： 塔里木盆地经历了多期构造运动的改造, 共形成了三大类, 六个亚类的不整合。这些不整合面(带)是油气良好的运移通道和有利的聚集场所, 它们对下伏地层的储集性能有很大的改造作用, 同时它们对早期油气藏又具破坏作用。另外, 它们还具重建封闭作用,有利于晚期成藏。不整合类型的差异性、继承性和迁移性控制油气藏的形成、演化和分布。断褶不整合和褶皱不整合是最有利的控油不整合。

Abstract: Tarim basin has undergone multi-stage tectonic movements, and formed three types composed of six subtypes unconformities. These unconformities were better passages for hydrocarbon migration and favourable places for its accumulation, which were of strong effect of transform action of underlying reservoir quality, but also of destructive effect on early formed reservoirs. In addition, they are favourable for late reservoir-formation because of their reconfining actions.It was the difference, inheritance and migration of unconformity types that controlled the formation, evolution and distribution of petroleum reservoirs. Fault-folded and fold unconformities are the most favourable controlling-oil ones.
