摘要
在松辽盆地北部扶杨油层油气藏类型、分布特征及与成藏条件空间分布关系分析的基础上 ,提出了该区扶杨油层油气藏形成与分布的 4个主控因素 :青一段有效源岩分布及青一段好盖层分布控制了扶杨油层油气藏的形成与分布 ;青一段超压、扶杨油层的低水位砂体和青山口组底部断层的发育是扶杨油层形成上生下储大面积岩性油藏的重要条件 ;地下水碰撞带为扶杨油气聚集成藏提供了水动力圈闭条件。
On basis of analyzing relations between types and distribution of reservoirs and space distribution of reservoir forming conditions, 4 major dominating factors of reservoir forming and distribution in Fuyang reservoirs in north of Songliao basin have been presented: forming and distribution of Fuyang reservoirs were controlled by distribution of effective source rocks and good cap rocks in Qing 1 formation; the important conditions of forming vast lithologic reservoirs with oil generation formations in the above and reservoirs below included overpressure in Qing 1 formation, sands with low water level in Fuyang reservoirs and development of faults in the bottom of Qingshankou formation; collision zone of underground water provided hydrodynamic entrapment for forming of Fuyang oil and gas reservoirs.
