| 摘 要： | 秦岭—大别造山带北侧存在多个盆地,其中有些盆地中已有一定的油气显示。近年来地质、地球化学研究成果表明,秦岭—大别造山带北侧主要发育6个世代的盆地序列,分别是:1)被动大陆边缘盆地(-C1—O2);2)弧后盆地(O2—C1);3)残余盆地(C2—T2),其中可分为残余盆地第1阶段(C2—P12)和残余盆地第2阶段(P12—T2);4)陆内前陆盆地(T3—J);5)张扭性盆地(J3—K1);6)断—拗盆地(K2—E)。秦岭—大别造山带北侧盆地发育6套烃源岩层系,分别是古近系、下白垩统、下侏罗统、上三叠统、石炭—二叠系和下古生界,并进行了相关烃源岩层系的成藏特征分析。东秦岭—大别山北侧主要勘探层系第一位的是石炭—二叠系,第二位是下白垩统,第三位是上三叠统,第四位是古近系,而中—下侏罗统及下古生界可列为第五位。建议勘探选区是一类盆地为周口盆地、济源盆地和洛—伊盆地。有利区带是谭庄—沈丘凹陷、倪丘集凹陷、襄城凹陷、舞阳凹陷、孟县—温县凹陷和洛阳凹陷。

| Abstract: | There are lots of basins which have contained some oil gas in near northern Qinling-Dabie mountain.The geological-geochemical research results showed that there are 6 basin generations in near northern QinlingDabie mountain: 1)passive continental margin basin(C1-O2),2)back-arc basin(O2-C1),3)residual basin(C2-T2),the stage 1(C2-P12) and stage 2(P12-T2),4)intracontinental foreland basin(T3-J2),5)extensional strike-slip basin(J3-K1),6)fault-depression basin(K2-E).Six source rock suites have been developed,Eogene system,Lower Cretaceous,Lower Jurassic,Upper Triassic,Carboniferous-Permian and Lower Palaeozoic in near northern Qinling-Dabie mountain.The main prospecting strata are Carboniferous-Permian,Lower Cretaceous,Upper Triassic and Eogene system in near northern Qinling-Dabie mountain.The Zhoukou Basin,Jiyuan Basin and Lao-Yi Basin are chosen as prospect.The Tanzhuang-Shenqiu Sag,Niqiuji Sag,Xiangcheng Sag,Wuyang Sag,Mengxian-Wenxian Sag and Luoyang Sag are chosen as favourite district. |
