大庆油田是我国重要的油气生产基地之一,然而多年的勘探开发,大庆油田已进入油气田勘探与开发的中后期阶段,目前正面临着储采失衡、资源接替不足的严峻局面,而大庆油区扶余油层具有较大的勘探开发潜力,是石油开采的主战场。因此,对扶余油层开展精细的高分辨率层序地层学及沉积相研究,总结油气富集规律,对油气勘探开发具有重要的指导作用和借鉴价值。本论文将以沉积学、高分辨率层序地层学理论为指导,综合应用地震资料、钻/测井资料、岩心资料对大庆南部扶余油层进行系统深入的层序地层研究。
Daqing Oilfield is one of the important oil and gas production bases in China. However, for many years of exploration and development, Daqing Oilfield has entered the middle and late stage of oil and gas field exploration and development. Currently, it is facing a severe situation of imbalance of reserves and resources and insufficient replacement of resources. However, Fuyu reservoir has great exploration and development potential, is the main battlefield of oil exploration. Therefore, the Fuyu oil layer to carry out fine high-resolution sequence stratigraphy and sedimentary facies, summed up the law of hydrocarbon enrichment, oil and gas exploration and development has an important guiding role and reference value. Based on the theory of sedimentology and high-resolution sequence stratigraphy, this paper will systematically study the sequence stratigraphy of the Fuyu oil reservoir in the southern part of Daqing using seismic data, drilling / logging data and core data.
