摘　　要：非常规油气勘探表明致密油气形成的有利区往往与深水砂岩分布区相关。目前国内通过露头研究储层尺度深水沉积体系或深水砂岩的工作非常薄弱,主要是缺少具体的研究方案。与传统露头资料相比,数字化露头资料和相应露头模型对于深水砂岩油气勘探开发会更有价值,但是露头建模仍是深水砂岩露头研究的难点之一。利用岩心研究深水砂岩的沉积环境及沉积相是分析储层尺度深水砂岩成因的有效手段。露头与岩心结合研究储层尺度的深水砂岩离不开测井和地震等资料,它们都是联系这些资料的重要桥梁。Unconventional oil and gas exploration shows that the favorable area of tight oil and gas formation is often related to the distribution area of deep-water sandstone. At present, the domestic research of reservoir scale deep-water depositional system or deep-water sandstone is very weak by outcrop, this is mainly due to the lack of specific research proposal. Comparing with traditional outcrop data, although digital outcrop data and corresponding outcrop models will be more valuable for deep-water sandstone oil and gas exploration and development, outcrop modeling is still one of the difficulties in the research of deep-water sandstone outcrops. Using core to study sedimentary environment and facies of deep-water sandstone is an effective way to analyze the genesis of deep-water sandstone at reservoir scale. The combination of outcrop and core to study deep-water sandstone at reservoir scale is inseparable from logging and seismic data, because they are all important bridges to connect these data.
