摘要:
基于苏北盆地金湖凹陷的地质及地球物理资料,根据区域构造演化背景和剖面,描述了该凹陷的构造特征,讨论了该凹陷西斜坡构造演化阶段,并探讨了其构造演化特征。结果表明:金湖凹陷西斜坡地区断裂构造发育,大部分断层弧形弯曲,断层以小级别断层为主,断层组合以拉张型为主,断块圈闭发育;西斜坡在新生代期间的构造演化可划分为斜坡发育阶段(古新世阜宁期)、差异抬升阶段(始新世戴南期—三垛期)、逆冲褶断阶段(始新世三垛期末)、构造稳定阶段(新近纪和第四纪)等4个阶段;新生代构造活动强弱交替,断层活动差异性明显,古新世阜宁期和始新世三垛期断层活动规模和活动强度较大,新生代整体持续西抬东降,有利于聚集来自斜坡东部深部凹陷的油气形成油气藏。
Abstract:
Based on the interpretation of geological and geophysical data in Jinhu Sag, Subei Basin, according to the background and section of regional tectonic evolution, structural feature of Jinhu Sag was described, the stages of tectonic evolution of western slope in the sag were divided, and the characteristics of tectonic evolution were discussed. The results showed that the fault structure developed in western slope of Jinhu Sag; most of the faults were curving, and faults were mainly in small level; combination of fault was mainly extensional, and the trap of fault block developed; tectonic evolution of western slope during the Cenozoic could be divided into slope developing stage(Paleocene Funing Period), differential fluctuation stage(Eocene Dainan-Sanduo Period), overthrust folded stage(Late Eocene Sanduo Period)and structure stable stage(Neogene and Quaternary); Cenozoic tectonic activity was strong and weak in turn; difference of fault activity was significant, and intensity and scale of faulting during Paleocene Funing Period and Eocene Sanduo Period were comparatively strong; faults rose west and descended east during Cenozoic, and it was favorable to accumulate the oil and gas from the deep sag of eastern slope and to form oil/gas reservoir.
