摘要(Abstract)：

为了满足大庆长垣外围油田厚油层测井细分解释的需要，解决复杂油水层识别和长垣外围厚层细分解释的问题，在对原储层参数解释模型进行补充完善的基础上，建立了深侧向电阻率校正模型，采用了平面分区、纵向分层、储层分类、分层厚的“四分”方式和综合指数、含油特性指数、含水特性指数、孔隙特性指数、油水比指数的“1C4 I”参数油水层精细识别方法，并建立了升平油田葡萄花油层产能预测模型，形成了低饱和度油层复杂储层精细解释配套技术；按照“有夹层细分、物性有差别细分、水淹级别不同（电性不同）细分”的原则，研发了基于GPTLog平台和CIFLog平台的细分层解释软件。实现了复杂油水层有效识别、多井自动细分层，形成了长垣外围油田厚油层测井细分解释配套技术。研究成果实现了长垣外围油田厚油层高效细分解释，同时可为低饱和度油层的精细解释提供参考。
In order to meet the demand of logging subdivision interpretation of thick oil layers in peripheral oilfields of Daqing Placanticline, and to solve the problems of complex oil and water layers identification and subdivision interpretation of thick oil layers in peripheral area of Placanticline, on the basis of supplementing and improving the original reservoir parameters interpretation model, deep lateral resistivity correction model is established, which adopts “four separation” method of areal zones partitioning, vertical layers separation, reservoirs classification and layers thickness dividing, as well as“ 1C4 I” parameters for fine identification method of oil and water layers, including comprehensive index, oil-bearing property index, water-bearing property index, pore property index and oil-water ratio index. Productivity prediction model for Putaohua reservoir in Shengping Oilfield is established, forming supporting technique for fine interpretation of complex reservoirs in low saturation reservoirs. Subdivided layers interpretation software based on GPTLog platform and CIFLog platform is developed according to the principles of “subdivision with interlayers, subdivision with different physical properties and subdivision with different wateredout levels(different electrical properties)”. Effective identification of complex oil and water layers and automatic subdivision of multiple wells are achieved, forming supporting technique for logging subdivision and interpretation of thick oil layers in peripheral oilfield of Placanticline. The research realizes efficient subdivision and interpretation of thick oil layers in peripheral oilfields of Placanticline, and provides reference for fine interpretation of low saturation reservoirs.
