本文论述了辽河拗陷的区域地质背景、构造和沉积特征、生油条件和生储盖组合关系、油藏类型及其分布规律。从而论证了它与渤海湾盆地其他拗陷的石油地质条件有许多相似之处,同时也具有一系列区别于其他拗陷的特点。构成一种很有特色的油气聚集区类型。
This paper discusses the regional geological background, tectonic and sedimentary characteristics, the relationship between oil-producing conditions and the reservoir-cap assemblage, the types of reservoirs and their distribution in Liaohe depression. Thus it is demonstrated that it has many similarities with the petroleum geology conditions of other depressions in the Bohai Bay Basin, and also has a series of characteristics distinguished from other depressions. Constitute a very unique type of hydrocarbon accumulation area.
