摘　　要：营城组地层是徐家围子断陷天然气勘探开发的主要目的层,通过对徐家围子断陷最新三维连片处理地震资料和区内探井的综合研究,一方面在地震剖面上从振幅、连续性及反射终止等方面指出了营城组各界面特征,另一方面又从钻井资料上总结了各界面在盆地不同部位岩性变化的多样性特征。同时,从层序演化、不整合范围、地层厚度及岩性变化特征等方面阐述了营城组四段应归属于登娄库组一段的观点。Yingcheng Group Formation is the main target area ot natural gas explorauon anu u p jiaweizi Rift. Based on the comprehensive study of the latest 3D sectors-connecting processing seismic data and the prospecting wells in research area, the author points out characteristics of boundaries of Yingcheng Group by amplitudes, continuity and seismic reflection termination on seismic profiles on the one hand, and summarizes diversified features of lithological change on well data in different areas of the rift on the other hand. The author also gives a view point that segment four of Yingcheng Group should be attributed to segment one of Denglouku Group by analyzing sequence evolution, the scope of unconformity, bedthickness and lithological change. All mentioned above have profound significance on guiding the layered of new well and enhancing the precision of exploration.
