摘　　要：低渗透砂岩油藏因其孔隙结构复杂,利用常规方法进行油水层识别和储层评价难度较大。地球化学技术可以直接分析储层样品的流体特征,测井技术特别是核磁共振测井能够提供更为丰富的储层响应特征。以商河油田基山砂岩油藏为例,介绍了以地质为主线,地球化学与地球物理测井相结合,从孔隙结构入手,利用多种资料和手段进行综合研究、评价低渗透砂岩油藏的方法,并在基山砂岩油藏储层的实际评价中取得了较好的效果。Because of complex pore structure in low permeability sandstone reservoir,it was quite difficult to identify oil or water layer and e-valuate reservoir using normal methods. Geochemical techniques could directly analyze the fluid features of reservoir samples, and well logging,especially NMR logging could reflect abundant reservoir response character. Then, a comprehensive evaluation method was introduced taking Jishan low permeability sandstone reservoir in Shanghe Oilfield as an example. Based on geology and combining geochemical and geophysical well logging, this reservoir was comprehensively evaluated and analyzed by this method using multiple data and approaches beginning from the pore structure, and obvious effect was acquired in evaluating Jishan sandstone reservoir.
