摘　　要：文章针对前震旦系变质岩储集层具有岩性特征、孔隙结构复杂及缝洞发育等特点,论述了利用多种测井信息综合评价裂缝性储集层的方法,其中包括变质岩的岩性特征分析。在分析岩石矿物成分的基础上,利用已知岩性与测井信息制作各种交绘图,总结、研究胜利油区前震旦系变质岩岩性划分方法及岩性识别特征,并对岩性种类进行了划分,结合变质岩的电性特征、成像测井、偶极子声波测井、自然伽马能谱测井等多种测井信息,进一步总结了岩性与储集段类别之间的关系。根据储集段的特征,建立测井评价模型,重新制定储集段类别划分标准,实践证明该套变质岩储层测井综合评价的方法与储集层的划分与以往方法相比更加趋于合理。Aimed at the characteristics of lithology, complex pore texture and developed fracture-cave of pre-Sinian metamorphics reservoirs, the methods of comprehensively evaluating fractural reservoirs with various log data are expounded. Including the lithology analysis of metamorphic rocks, on the basis of analyzing the mineral components, making diversified cross-plots with known lithology and logging data, the methods of dividing pre-Sinian metamorphic lithology and identifying lithology features in Shengli oil field are Summarized and investigated, and then, the lithology types are divided. Combining various logging data, such as electric character, imaging logging, XMAC, nature gamma spectrum etc. the relationship between the litholgy and reservoir type is further summarized. According to the reservoir characteristics, the logging evaluation model is set up and the reservoir division standard is re-made. It is proved by practices that the methods of integrally evaluating and dividing metamorphic reservoir are more reasonable than those previous.
