Abstract


Northern Jiangsu area since Cenozoic tectonic movement frequently , multi-phase basins superimposed , composite , together with the non-rigid substrate makes the internal structure of the basin broken . Southern boundary the the Zhenwu fault as in Gaoyou Sag , complex structural features . Faults at all levels in Gaoyou Sag control concave fault really ① active faults under the influence of both the similarity and differences . Fault Distribution Law Zhenwu fault zone , the development and evolution of the characteristics and causes of the research has important theoretical value guide oil and gas exploration , the search for the target . The thesis structure study of geometry, kinematics theory as a guide , combined with seismic profiles , logging data , and a variety of geological data , structural and stratigraphic interpretation of the typical profile ; Zhenwu fault zone fracture characteristics , the strength and activity of the fault activity law , tectonic evolution and genetic mechanism . According to the geometric characteristics of the analysis Zhenwu fault zone will be divided into three sections , paragraphs fault strike , shape , profile occurrences fracture combined features and distribution of lower order faults are different . By calculating the average activity rate of the major faults of each period , the preparation of the faulting cycle diagram summarizes the major fault activity intensity and activity patterns ; to select appropriate depth profile analysis of fault zone tectonic evolution , summed up the a major fault developmental history and evolution of . That really ② fault shallow divided into true ② The -1 true ② The -2 really ② -3 three sections , deep merged into a fault , and generally true ② fault segment Zhenwu fault zone fault zone development mode . Accommodation zone within the fault zone signs identify the fault geometry characteristics , formation thickness and depth of activity features of its the divided type and grading . Adjust Structural characteristics analysis , and uneven stretching role ; differences in sexual activity of the fault ; the fault plane developmental mode , and adjust the structure of the joint , overlay and migration is adjusting band formed the zhenwu fault zone . Explain the causes constituting zhenwu fault zone fault : the fault geometry inheritance and border concave side \
