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.
Abstract
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,gener-ally develops low resistivity reservoir.Due to the complex genesis and types of low resistivity reservoir,low resistivity reservoir have different petrophysical and log response characteris-tics.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 charac-teristics of low gas content,the resistivity characteristics and gas content are difficult to dis-tinguish 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 im-proved,which provides a strong basis for the development and deployment of P oilfield.
