摘　　要：总结近年来油田开发基础研究手段方法方面的进展,以及老油田和陆相页岩油开发提高采收率新方法的研究和试验进展,分析各类方法存在的问题、提出下一步研究方向与建议。阐述了原位获取地下岩石/流体样品与无损检测分析等基础研究手段的进展,综述了“纳米水”驱等改善水驱,低浓度中相微乳液驱等化学驱,微纳米气泡驱等气驱,注空气热辅助混相驱等热采,以及密切割均匀压裂/无水压裂等常规油和页岩油提高采收率新方法的驱油机理、技术路线、关键技术研究与矿场试验进展。油田开发提高采收率新方法研究已取得了显著的进展,有些已在矿场试验中取得了良好的初步效果,但仍然面临机理研究欠深入、方法和配套工艺待完善、产业链不完整等问题,建议持续加强基础研究、加大现场试验规模,进而促进新技术系列的形成和推广应用。This paper reviews the basic research means for oilfield development and also the researches and tests of enhanced oil recovery(EOR) methods for mature oilfields and continental shale oil development,analyzes the problems of EOR methods,and proposes the relevant research prospects.The basic research means for oilfield development include in-situ acquisition of formation rock/fluid samples and non-destructive testing.The EOR methods for conventional and shale oil development are classified as improved water flooding(e.g.nano-water flooding),chemical flooding(e.g.low-concentration middle-phase micro-emulsion flooding),gas flooding(e.g.micro/nano bubble flooding),thermal recovery(e.g.air injection thermal-aided miscible flooding),and multi-cluster uniform fracturing/water-free fracturing,which are discussed in this paper for their mechanisms,approaches,and key technique researches and field tests.These methods have been studied with remarkable progress,and some achieved ideal results in field tests.Nonetheless,some problems still exist,such as inadequate research on mechanisms,imperfect matching technologies,and incomplete industrial chains.It is proposed to further strengthen the basic researches and expand the field tests,thereby driving the formation,promotion and application of new technologies.
