利用地震属性、碎屑岩岩性和骨架颗粒成分、重矿物组合、ZTR指数和倾角测井资料,为确定沙二段物源体系进行了研究。结果表明歧口凹陷沙二段发育6大物源体系:燕山褶皱带、沧县隆起、港西凸起、孔店凸起、埕宁隆起和沙垒田凸起。沧县隆起物源有葛沽、小站、增幅台和沈青庄4个物源口;歧北次凹是混合物源区,物源为北部燕山褶皱带和港西凸起。通过研究分析确定了各个物源体系的波及范围。
Based on the seismic attributes, lithology and composition of skeleton rocks, heavy mineral assemblage, ZTR index and dip logging data, a systematic study was carried out to determine the source system of Es2. The results show that there are six major source systems in the second member of the Qikou depression: the Yanshan fold belt, Cangxian uplift, Gangxi uplift, Kongdian uplift, Suining uplift and Shaleida uplift. Cangxian uplift source Gegu, station, increase Taiwan and Shen Qing Zhuang four source mouth; Qubei sub-concave is a mixture of source area, the source for the northern Yanshan fold belt and the western part of the bulge. Through research and analysis to determine the scope of the various source systems.
