松辽盆地南部十屋断陷北部深层油气成藏条件

运用层序地层学分析的方法，综合分析了松辽盆地南部十屋断陷北部深层隐蔽油气藏成藏条件。表明断陷北侧是主要的物源区，有利储集体主要分布在弯折带内，尤其是沙河子组和营城组沉积时期沿弯折带走向成裙状分布，伸入到南侧深洼的低位扇和高位轴向辫状河三角洲朵体应该成为十屋断陷隐蔽油气藏成藏的主要勘探方向。

Conditions of Hydrocarbon Accumulation of Deep Reservoirs in the North of Shiwu Fault Depression in the South of Songliao Basin

A method of sequence stratigraphic analysis is used to integrally analyze the conditions of hydrocarbon accumulation in the north subtle reservoirs in Shiwu Fault Depression in the South of Songliao Basin. It indicates that the main source area is in the north side, the beneficial reservoirs are mainly distributed in the rupture zones. Especially during the depositional periods of Shahezi Formation and Yingcheng Formation, it is distributed in skirt shape along the rupture trend, the braided river delta in high axis and low fan intruded into the south deep depression shall be the main directions of subtle reservoir formation in Shiwu Fault Depression
