摘要
河口构造位于辽河坳陷西部凹陷南部，油气产层沙河街组二段埋深超过3500m，油气性质较好，已探明石油地质储量238×10^4t。河口构造油气藏的形成，除具有油源充足、存在有利圈闭、运聚匹配良好等有利条件外，其储层条件是制约油气成藏的关键。该构造储层属扇三角洲前缘亚相的水下分流河道微相沉积，并存在由成岩作用形成的次生孔隙发育带。
Hekou area lies in the southern part of Shuangtaizi-Shuangnan faulted anticlinal structural belt of the west sag of Liaohe depression. There proved 238 × 104t petroleum-in-place in the Sha-2 memberl under 3500m of Shahejie Formation. Hekou structure is characterized by abundant hydrocarbons and good match of source,reservoir and caprock. Its reservoir with secondary porosity zone is also a key for petroleum pool formation,which is of distributary channel of fan delta front.
