摘要
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E_1f_2—E_1f、K_(2t_1)+K_(2c)(！),E_1f_4—E_2d、E_2s(！)和K_2t_2—K_2t_1+K_2c、E_1f(·)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。
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.
