FAULT ACTIVITY FEATURES OF TONGCHENG FAULT ZONE IN JINHU SAG

Faculty of Earth Science and Technology, China University of Petroleum, Qingdao 266580, Shandong, China

摘要

摘要: 通过地震和地质资料解析, 分析了铜城断裂带的构造特征, 讨论了构造演化阶段及特征。研究表明, 铜城断裂带多发育北东走向的断裂构造, 阜宁期和三垛期是断层集中发育的阶段, 阜宁期掀斜旋转明显, 断块、断鼻构造发育。铜城断裂带新生代断层活动性表现出强弱交替的特征, 断层活动性复杂。阜宁期断层活动性加强, 戴南期相对较弱, 三垛期断裂活动又增强, 此后, 断层活动基本停止。铜城断层两侧地层差异沉降明显。铜城断裂带构造演化经历断块发育期(E₁f)、差异沉降期(E₂d-E₂s)、逆冲褶断期(E₂s末期)、构造稳定期(Ny-Qd)等4个时期。在吴堡运动、三垛运动的叠加与早期基底断层的共同作用下, 铜城断裂带形成断鼻构造、复杂断块构造及弧形断层圈闭, 为油气聚集提供良好的场所。

Abstract: According to the interpretation of information of seismology and geology, structural features of Tongcheng fault zone is analyzed; the features and the stages of tectonic evolution are discussed. The research shows that the Tongcheng fault zone mainly develops NE-SW strike faults. Most faults are formed in the Funing period and Sanduo period. Tilt rotation of the blocks is obvious. The structures of fault block and fault nose are developed. Cenozoic tectonic activity shows alternating strong and weak characteristics, and fault activity is complex. The intensity of fault activity in Funing phase is gradually strengthened, and become relatively weak in Dainan period, In the Sanduo phase fault activity enhances, then fault activity largely discontinues. The differential fluctuation in Tongcheng fault is obvious on both sides of strata. Tectonic evolution of Tongcheng fault zone can be divided into four period: fault block development stage (Funing period), differential fluctuation stage (Dainan and Sanduo period), overthrust folded stage (Late Sanduo period), structure stable stage (Neogene and Quaternary). With the superposition of Wubao movement, Sanduo movement and early influence of basement faults, Tongcheng fault zone causes the development of fault nose structure, complex fault block structure and arc fault trap, which provides good places for oil-gas accumulation.
