Abstract：Located in the eastern part of the central uplift belt,Dongxin area in Dongying Sag,10 accommodation zones of subtle faults are identified and classified into 5 types.Structural characteristics of different types of fault accommodation zones and the relationship with the hydrocarbon distribution are detailedly analyzed,and seismic identification marks of different types are constructed.Collateral fault accommodation zones mainly developed in Xinzhen structure are paralleled major faults with step-fault patterns or multiple graben patterns on sections.Overlapping accommodation zones mainly developed in Dongying structure are obliqued with major faults in en echelon arrangement in the plane and their structural style is presented in horsetail patterns and flower structure on sections.Approaching accommodation zones formed by one major fault of Dongying structural belt adjoining other 3 major faults of Xinzhen structural belt are fan-like in plane.On sections,their structural style is presented the patterns of compound flower structure.The accommodation zones controlled by single major fault are divided into the types of inward convergence to hinge zone and divergency in pitching end.The inward convergent accommodation zones developed in northwest part of Dong-ying structure are distributed in the manner of brush convergent to major faults with the patterns of pectination on sections.Whereas,fault accommodation zones of divergency in pitching end developed in the west of Xinzhen structure are distributed in the manner of phoenix tail in plane.On sections,the lower structural style is presented in the patterns of pectination and the upper structural style is presented in pattern of cabbage liking.Collateral accommodation zones and inward convergent accommodation zones can be easily identified with coherence attribute and seismic sections.Then overlapping accommodation zones and approaching accommodation zones can also be identified.The most difficult to be identified is the fault accommodation zones of divergency.The collateral accommodation zones and overlapping zones are the most prolific hydrocarbon areas in Dongxin Fault Zone because their development and activity had a very close relationship with oil source fault activity.The conclusions are instructive and meaningful to fault accommodation zone identification and favorable target optimization in the transtensional fault system.
