摘　　要：目的揭示断陷盆地层间地质体的成藏规律。方法以层序地层学理论为指导,结合沉积相研究,综合应用了3D Canvas地震解释技术、Geoprob立体显示技术、相干体技术、水平切片识别技术及Voxgeo立体显示技术。结果在贝中次凹发现构造圈闭17个,南屯组油气主要集中在层间构造上,长期的断裂活动控制了油气的运移和分配。结论断陷盆地小凹陷层间构造控制了油气的聚集,如果有好的成藏条件具有勘探潜力。Aim To show regulation of reservoir formation of interlayer geo in break sedimentation basin. Methods Guided by the theory of sequence stratigraphy ,the following techniques are used： 3D Canvas seism interpretation,Geoprobe lithological trap identification, coherent data volume analysis, leveling layer slice identification and so on. Results The seventeen structure traps have been found in Beizhong sub-depression. Oil and gas of Nantun Group mainly concentrate on the interlay geologic structure. Lasting fracture activities control hydrocarbon movement and distribution. Conclusion Interlayer geologic body controls the hydrocarbon accumulation. It will have exploration potential in the case of well conditions of reservoir formation.
