伊朗Kashan地区库姆盆地层序地层及沉积体系分布
|
摘要
中伊朗库姆盆地Kashan(卡山)地区是中国石化海外重要的勘探区块,并首钻ARN-1井成功。该区是始新世中期—中新世中期形成的一个弧后边缘海盆地,其库姆组以浅海相的碳酸盐岩和碎屑岩沉积为主。依据野外露头、钻井、测井、地震等资料建立了库姆组层序地层格架,划分为2个二级层序(SS1和SS2)和5个三级层序即S1—S5。并通过层序地层的划分对比分析了该区各层序的沉积体系的演化及展布特征,主要为三次海侵形成三期沉积体系:即S1层序为初次海侵期(A,B段,C1亚段),S2层序为沉降充填期(C2,C3,C4亚段),S3—S5为再次海侵期(D—E段)。最后探讨了油气勘探意义。
The central Iran basin is a back-arc marginal sea basin formed in Late Oligocene to Early Miocene with mixed carbonate,evaporites and clastics succession.Based on the integrated study on the sufficient outcrops,wells,loggings and seismic profiles,the sequence stratigraphy framework of Qum Formation was set up.Two second-order sequences(SS1 and SS2)and five third-order sequences(S1-S5)were identified in Qum Formation.This paper analysized sedimentary system evolution and distribution of each sequence period.The results indicted that three times transgression dominated three periods of sedimentary system evolution.They are:sequence S1,the first transgression period(A,B members,C1 sub-member),sequence S2,the subsidence filling period(C2,C3,C4 sub-members),sequences S3-S5,the transgression period again(D-E members).Finally,the authors discussed its signiffcance for oil-gas exploration.
