白音查干凹陷锡林好来构造区油藏类型丰富，储层复杂多样。受岩性、矿物成分和成岩作用等影响，油层“四性”特征复杂。砂砾岩类储层因油层与围岩电阻率持平，导致油层易被遗漏；白云质泥岩缝洞型储层则存在缝洞型油层识别难的问题。文中综合利用岩心、岩屑、测井及试油、开发生产资料，分析不同类型储层的“四性”特征；通过绘制不同测井参数的散点交会图，研究不同岩性储层的岩电参数特征，并确定不同储层中油层的测井解释参数界限，从而提高了对油层的识别能力。在此基础上，制定了不同岩性储层中油层压裂改造的界限参数，对锡林好来及其相邻的达尔其构造区分井开展了油层的二次评价，对提高研究区勘探开发整体效益具有一定的指导意义。

There are lots of oil reservoir types in Xilinhaolai structure region of Baiyinchagan Sag. The reservoir is complicated and the four properties of the oil layer are complex under the influence of the lithology, mineral components and diagenesis. For glutenite reservoirs, the oil layer has always been omitted because its resistance is close to that of surrounding rock. For fractured-vuggy reservoir with dolomitic mudstone, it is difficult to identify the fractured-vuggy oil layer. Through the comprehensive utilization of the core, debris, logging, oil test and production data, the four properties of different type of reservoir were analyzed. By drawing the scatter cross plot of different logging parameters, the lithologic and electrical characteristics of the oil layer were studied. And the parameter limit of log interpretation of the oil layers in different type of reservoirs was defined. The recognizing ability on oil layers is improved. On these bases, the boundary parameters were defined for different type of reservoirs which can be used to determine to fracture the poor deposit or not. Further evaluation of oil layer was carried out for some wells in Xilinhaolai structure and the adjacent Daerqi structure. It has certain guiding significance for improving the whole benefits of exploration and development in studied areas.
