辽河西部凹陷隐蔽油藏分布广泛，规模较大，地质储量占总地质储量的40％左右，分析其原因在于，该地区其有形成隐蔽油藏的良好地质条件：〈1〉块断结构；〈2〉小型断陷湖泊沉积；〈3〉广泛的地层超覆不整合；〈4〉丰富的油源。文章分析了凹陷内隐蔽油藏的七种主要类型及其具体形成条件和分布状况，并在此基础上进一步讨论陆相箕状断陷内隐蔽油藏分布的一般模式。
The hidden reservoirs in the western Liaohe depression are widely distributed and large in size, and their geological reserves account for about 40% of the total geological reserves. The reason for this analysis is that they have good geological conditions for forming subtle reservoirs in the area: <1> 2> small rift lacustrine sediments; <3> extensive stratigraphic unconformity; <4> rich source of oil. This paper analyzes the seven major types of hidden reservoirs in the depression and their formation conditions and distributions. On this basis, we further discuss the general pattern of subtle reservoir distribution in the continental half-graben fault.
