苏北盆地高邮凹陷含油气系统与油气勘探

高邮凹陷油气资源丰富,成藏条件优越,具有三套烃源岩、九套储集层、三套区域盖层和多套局部盖层、七套有利储盖组合、多种圈闭类型、两种油气运移通道和多种油气成藏模式,可划分出E₁f₂—E₁f、K_2t1+K_2c（！）,E₁f₄—E₂d、E₂s（！）和K₂t₂—K₂t₁+K₂c、E₁f（·）三个含油气系统。研究表明,各含油气系统仍具有较大的勘探潜力和众多的有利勘探目标。

The Petroleum System and Petroleum Exploration of Gaoyou Sag in Subei Basin.

Gaoyou sag is of abundant petroleum resources andsuperior petroleum geologic conditions. There arethree source rocks, nine reservoir rocks, three regionalcaprocks and several reginal caprocks, seven favor-able reservoir-caprock compositions, several traptypes, two petroleum migration paths and several poolformation models. Three petroleum systems E_1f_2-E_1f,K_2t_1 K_2c(!),E_1f_4-E_2d, E_2s(!) and K_2t_2-K_2t_1 K_2c, E_1f(.)are divided, and they are of larser exploration poten-tialities and many favorable exploration targets.
