Abstract: Focusing on the characteristics of China’s continental shale oil and the difficulties in sweet spot evaluation, this paper analyzes the common and special technical requirements of shale oil exploration and development for seismic prospecting, and describs the development status of continental shale oil seismic prospecting technology at home and abroad from the aspects of seismic prospecting data acquisition, processing, interpretation and sweet spot prediction. Foreign countries pay more attention on the effective utilization of 3D seismic data, while China puts more efforts to make a breakthrough in the predication and comprehensive evaluation of sweet spot factors. At present, China has established a relatively complete technical system, and has also achieved certain application effects, and is in a leading position. Seismic prospecting for continental shale oil in China has identified several key technologies. Seismic acquisition and imaging processing technologies for shale oil-gas are not fundamentally different for conventional oil and gas, and the prediction technologies of favorable lithofacies, thin interlayer, physical properties, brittleness, fractures, formation pressure, and geo-stress as well as the comprehensive evaluation of sweet spots are key technologies. Seismic prospecting of continental shale oil needs to improve the prediction accuracy of sweet spots, continuously improve the prediction technologies such as lithofacies, fractures, pore pressure and stress, deepen the seismic and geological and engineering integration, and promote the effective application of artificial intelligence on shale oil evaluation.

Key words: continental shale oil, seismic prospecting, sweet spot prediction, integration of geophysics and geology with geomechanics, artificial intelligence

摘要: 针对陆相页岩油的特点和"甜点"评价难点,分析了页岩油勘探开发对地震勘探的共性和特殊的技术要求,并从地震勘探资料采集、处理、解释和"甜点"预测等方面,阐述了国内外陆相页岩油地震勘探技术发展现状。国外重视三维地震资料的有效利用;中国着力攻关"甜点"要素的预测与综合评价。中国目前已建立了一套相对完整的技术体系,也取得了一定的应用效果,处于领先地位。中国的陆相页岩油地震勘探已明确几项关键技术。页岩油气的地震采集和处理成像技术与常规油气没有本质不同,有利岩相、薄夹层、物性、脆性、裂缝、地层压力和地应力等预测技术及"甜点"综合评价是关键技术。陆相页岩油地震勘探需要提高"甜点"预测精度,持续攻关岩相、裂缝、压力、应力等预测技术,深化地震—地质—工程一体化,并推进人工智能的有效应用。
