摘　　要：为尽快形成与页岩油勘探开发相配套的测井评价技术,在对国内外页岩油气最新研究成果,尤其是北美页岩气测井评价现状调研的基础上,结合区域地质特征,得出东濮凹陷页岩油测井评价的关键是复杂岩性划分、矿物成分分析、地化参数评价和储层划分标准建立,可通过岩石物理实验、优化测井系列、创新解释方法、完井后评价等4项措施可有效解决之。形成了空气、油基泥浆、水基泥浆等不同钻井介质下的测井系列,增强了测井资料采集的适应性。The matching technology of well logging evaluation for shale oil exploration and development has been researched based on the latest achievements at home and abroad,especially based on investigation of well logging evaluation for shale gases in North America with combination of regional geological features.It has been concluded that the keys to well logging evaluation of shale oil reservoir in the Dongpu sag are classification of complex lithologies,mineral composition analysis,evaluation of geochemical parameters,and establishment of reservoir zonation criteria.Effective measures may involve rock physics experiment,optimized logging suite,innovative method of logging interpretation,and evaluation after well completion.The adaptability of well logging data acquired has been enhanced;the logging suite is suitable for air drilling,oil-based and water-based drilling fluids.
