摘要
应用层序地层学的原理和方法,综合运用地震、测井与钻井资料,对陆家堡凹陷西部地区九佛堂组层序和体系域边界进行了研究,并探讨了层序发育与沉积序列关系及其分布特征。结果表明,研究区九佛堂组可划分为1个三级层序和3个体系域。低位体系域由3个准层序组构成,自下而上沉积水体加深;湖侵体系域可细分为4个准层序组,总体表现为退积式和加积式叠置样式;高位体系域可划分为4个向上砂地比增大的进积准层序组。研究区在3个体系域沉积时期的地层厚度变化不同,在低位体系域沉积时期主要沉积中心位于包日温都断裂带北部,之后向西南迁移至包日温都断裂带中段与五十家子庙洼陷南部交界处。
The application of principles and methods of sequence stratigraphy, integrated with the seismic, logging and drilling data, we research the sequences and system-tracks for the Jiufotang formation in the west area of Lujiapu sag, and the 2 third grade sequence interface, the 3 fourth grade sequences or system-tracks, are all identified, which including the lowstand system-track, lacustrine transgressive system tract, highstand system-track, and they can be divided separately into 3, 4 and 4 subsequence sets. Thus, the sequence stratigraphy framework for the target formation of project area were formed, analysis system domain characteristics and plane exhibition cloth characteristics and the relationship between sequences growth and sedimentary succession and their distribution characteristics in horizontal and vertical direction, finally, the research achievement can provide a foundation for the further exploration of target formation.
