摘要
从构造、断裂系统、沉积因素等方面，阐述了冷东地区油气富集规律。提出构造活动控制生储条件；断裂系统控制圈闭和油气聚集；多期成因类型的砂砾岩体是油气聚集的场所；有利构造与岩相带匹配是油气富集的关键。油气分布具有“上稠下稀、东稠西稀”的特点。
The regular pattern of hydrocarbon accumulation in Lengdong area is discussed based on its structure, fracture system and sedimentary element etc.This paper advances that oil generating and storing conditions are controlled by tectonic movement ;traps and hydrocarbon accumulation are controlled by fracture sytem;hydrocarbon accumulates at glutenite of multiperiod origins and hydrocarbon accumulation depends on favourable structure and perofacies match.Hydrocarbon distribution feature is that oil in the upper formation is heavy,oil in the lowwer formation is light,and oil in the eastern area is heavy,oil in the weatern area is light.
