| 摘 要： | 本文对南华北盆地进行了深入细致的研究后认为其经历了12个演化阶段:变质结晶基底的形成(Ar-Pt1)、拗拉槽-裂谷盆地阶段(长城纪Ch)、克拉通—裂谷盆地阶段(蓟县纪Jx-新元古代青白口纪Qb)、克拉通-被动大陆边缘盆地阶段(Z-O2)、整体隆升-弧后盆地阶段(O3-D2)、克拉通-(弧后)前陆盆地阶段(D3-T1)、印支运动阶段(T2-T3)、类前陆盆地阶段(T3-J2)、压扭背景下的挤压冲断-走滑拉分盆地阶段(J3-K11)、冲断抬升剥蚀阶段(K21-K2)、裂陷盆地阶段(E)及坳陷盆地阶段(N-Q)。南华北盆地石炭-二叠系煤系地层是南华北盆地的主要烃源岩。石炭-二叠系煤系地层经历了沉积→埋深→抬升剥蚀改造→再埋深的过程,在再次埋深过程中具备二次生烃的条件。

| Abstract: | Our study indicates that the south part of the North China Area is a Meso-Cenozoic basin intimately related with the Qinling-Dabie orogenic belt. The tectonic stages for the south of the North China Basin include: formation of the metamorphic crystalline basement (Ar-Pt_1), aulacogen-rift basin (Ch), craton-rift basin (Jx-Qb), craton-passive continental margin basin (Z-O_2); uplift and back-arc basin (O_3-D_2), craton and (back-arc) foreland basin (D_3-T_1), Indo-Sinian movement (T_2-T_3), homogenous foreland basin (T_3-J_2), compressional thrust and pull-apart basin (J_3-K~1_1); thrust, uplift and denudation (K~2_1-K_2), rift basin (E) and depression basin (N-Q). Coal measure strata of Permo-Carboniferous are the major hydrocarbon source rocks in the south of the North China Basin. After deposition, burial, uplift, denudation and re-burial, hydrocarbon can be regenerated in the re-buried coal measure strata of Permo-Carboniferous, and the coal measure strata hence became the major targets for oil and gas exploration in the south of the North China Basin. |
