摘要:
为示踪陆丰13东洼文昌组东北向长轴辫状河三角洲砂体物源,对研究区6口井11个砂岩岩屑样品进行了碎屑锆石U-Pb定年分析,结果表明以岩浆成因为主的锆石年龄谱具有多峰特征,主峰值年龄为156、430 Ma。结合源区基底残留地层的岩性特征、年龄特征,辅以薄片岩屑类型鉴定和重矿物物源示踪,分析认为文二段、文五段物源主要为中生代沉积岩,局部可能受到始新世喷出岩、中生代花岗岩物源的影响,而不是早期研究认为的文昌组物源以中生代花岗岩为主。这些认识解释了陆丰13东洼文昌组发育优质储层的根本原因,同时也为今后本区源-汇体系研究及优质储层预测提供了新的依据
Abstract:
To trace the provenances of sandbodies in the northeastern long-axis braided river delta of Wenchang Formation in Lufeng 13 eastern sag, 11 sandstone cuttings samples from 6 wells in the study area are used to carry out a detrital zircon U-Pb dating analysis. The results show that the zircons are dominated by magmatogenic and the zircon age spectrum has multi-peak characteristics, with the main peak ages of 156 Ma and 430 Ma, respectively. Combined with the lithologic and age characteristics of basement residual strata in the source region, supplemented by thin section analysis of debris types and provenance tracing of heavy minerals, it is considered that the provenances of the second and fifth members of Wenchang Formation are mainly Mesozoic sedimentary rocks, which may be partially affected by the provenances of Cenozoic Eocene extrusive rocks and Mesozoic granites, rather than the previously considered Mesozoic granite provenance of Wenchang Formation. These understandings explain the fundamental reason for the development of high-quality Wenchang reservoirs in Lufeng 13 eastern sag, and provide a new basis for future study on source-sink systems and prediction of high-quality reservoirs in this region
