摘　　要：渤海P油田馆陶组纵向上存在多套流体系统,砂体叠置关系和油水界面复杂,普遍发育低阻油层。由于低阻油层的成因和类型复杂多样,导致低阻油层具有不同的岩石物理和录、测井响应特征。依据常规测井所建立的评价方法往往会低估甚至遗漏低阻油层,尤其当低阻油层同时具有低气体含量特征时,电阻率特征和气体含量与水层难以区分。结合以岩屑为测量载体的地化录井、三维定量荧光录井等技术,优选评价参数,建立多元综合评价方法。通过验证,大大提高了研究区低阻油层的快速识别符合率,为P油田开发部署提供了有力的依据支撑。There are many sets of fluid systems in the Guantao formation of P oilfield,Bohai Sea,and the relationship between sand bodies and oil-water interface is complicated,generally develops low resistivity reservoir.Due to the complex genesis and types of low resistivity reservoir,low resistivity reservoir have different petrophysical and log response characteristics.The evaluation methods based on conventional logging tend to underestimate or even omit the low resistivity reservoir,especially when the low resistivity reservoir has the characteristics of low gas content,the resistivity characteristics and gas content are difficult to distinguish from the water layer.Combined with geochemical logging and three-dimensional quantitative fluorescence logging,the evaluation parameters were optimized and a multi-component comprehensive evaluation method was established.Through the verification,the fast identification coincidence rate of low resistance reservoir in the study area is greatly improved,which provides a strong basis for the development and deployment of P oilfield.
