唐庄地区沙河街组构造特征及油气富集

Structural characteristics and hydrocarbon accumulation in Tangzhuang Shahejie formation

利用测井资料合成地震记录对三维地震剖面进行标定,以此为基础对唐庄地区沙河街组构造进行精细解释。构造研究发现,唐庄地区断层极为发育,平面和剖面组合形态多样,组成不同类型构造带。通过对构造特征和油气分布特征的综合分析认为,断裂控制了唐庄地区油气运移和聚集,并指出了油气聚集的有利区域,为后期油气开发提供了依据。

Fine structure interpretation has been conducted for the Shahejie formation in Tangzhuang area by demarcation on 3D seismic profile using synthetic seismogram made from logging data. Structure study shows that faults were very developed in this area with a variety of configurations in both areal and vertical directions thus formed different structural zones. Comprehensive analysis on structural characteristics and hydrocarbon distribution shows that the faults had controlled hydrocarbon migration and accumulation in Tangzhuang area. Favorable zones of hydrocarbon accumulation are pointed out, thus providing basis for future development.
