摘要：
The main fault zone in Shunbei area is favorable for hydrocarbon accumulation. In order to clarify the control effect of the strike-slip fault on oil and gas reservoirs in this area, through the fine interpretation of the 3D seismic data of the mid-north part of Shunbei No. 5 strike-slip fault zone, and combined with the previous research results and oil and gas exploration practices, in this paper it discusses the differential activity characteristics and reservoir control effect of the mid-north part of Shunbei No. 5 strike-slip fault. The study shows follows. (1) The Paleozoic of the Shunbei No. 5 strike-slip fault zone is dominated by linear and en echelon normal faults, and the plane distribution of Mesozoic-Cenozoic faults has almost no spatial relationship with Paleozoic faults; the deeper part of the profile is characterized by steep strike slip fault, and the middle to shallow part are flower structure. (2) Shunbei No. 5 strike-slip fault zone is characterized by distinct activity and can be subdivided into 16 segments, including strike-slip extrusion, strike-slip extension and pure strike-slip. (3) Shunbei No.5 strike-slip fault zone has experienced multi-stage structural movement superimposition transformation, among which the main active periods are Middle Caledonian Ⅰ, Middle Caledonian Ⅲ, Late Caledonian-Early Hercynian and Middle-Late Hercynian. (4) The differences in the plane segmental pattern, vertical structural pattern and activity of the strike-slip fault zone cause the differences in the scale of reservoirs and reservoirs in different parts of the same fault zone. © 2023 China University of Geosciences.
