Accurate determination of the effective period of oil and gas transported by the oil-source fault in the combination of source rock and reservoir separated by caprock plays an essential role in identifying the oil and gas distributions and guiding oil and gas exploration. Based on the study of the oil-gas transport mechanism and effective period by the oil-source fault of reservoir separated by caprock, a set of determination methods of the effective period for transporting oil and gas by the oil-source fault of reservoir separated by caprock was established by coupling the period for transporting oil and gas by the oil-source fault and the period when the source rocks expel hydrocarbon. In which, the determination of the period for transporting oil and gas by the oil-source fault was by determining the period when the faults start to destroy the sealing capacity of the mudstone caprock, the period when the faults stop their activity and the period when the fault fillers begin sealing, and the geochemical characteristics of the source rock were used to determine the period when the source rocks expel hydrocarbon. The application results show that, at line L2, the effective period for transporting oil and gas from the F1 oil-source fault to the reservoir of Dong 1 Member (Ed1) is relatively long, with a time of 5.3 Ma, which is conducive to transport oil and gas generated by the source rocks of Sha 1 Member (Es1) ~ Dong 3 Member (Ed3) through the mudstone caprock of Dong 2 Member (Ed2) to accumulate in the reservoir of Dong 1 Member (the upper part of the structure has not been drilled yet); at line L8, the effective period for transporting oil and 1基金项目：国家自然科学基金项目“砂泥岩层系中油源断裂输导油气优势路径演化及识别研究”（编号：41872157）、“断砂配置侧向分流运聚油气机理 及有利部位识别研究”（编号：42072175）。 第一作者简介：梁木桂，男，（1991-），汉族，广东省阳山县人，博士生，主要从事油气藏形成与保存研究。黑龙江省大庆市，东北石油大学地球科学学 院，联系电话：13039875182。Email: 1804690992@qq.com 通讯作者简介：付广，男，（1962-），满族，辽宁省新宾县人，博士，东北石油大学教授、博士生导师，主要从事油气藏形成与保存研究。黑龙江省大庆 市，东北石油大学地球科学学院，联系电话：13836918066。Email: fuguang2008@126.com 《工程科学学报》录用稿，https://doi.org/10.13374/j.issn2095-9389.2021.01.28.001 ©北京科技大学 2020 录用稿件，非最终出版稿
