摘要
海拉尔盆地为中新生代的多旋回、断一坳叠合型陆相断陷盆地。通过分析该盆地乌南次凹的构造、沉积、油气成藏特征，认为断陷盆地的油气生成于成熟的烃源岩区自源封闭的成藏系统中。剩余资源主要赋存于生烃凹陷水进体系域和高位体系域的致密砂岩、粉砂岩互层内，是非常规油气赋存的有利区带，应作为下一步非常规油气藏勘探的重点。
Hailar Basin is Mesozoic-Cenozoic polycyclic and fault-depression composite continental rifled basin. Through the analyses of the structures, sedimentations, hydrocarbon accumulating characteristics and sedimentary environments for Wunan Sub-sag in the basin, the hydrocarbon in the fault basin is mainly generated around the mature source rock area and self-enclosed accumulating system with short-distance migration. The rest resources are enriched in the tight sandstone-siltstone interbeds of water-transgression and high-stand system tracts of the hydro- carbon-generating sag, these areas are the the favorable plays of the unconventional oil and gas, so the further ex- ploration of the unconventional oil and gas reservoirs should be focused on these regions.
