摘　　要：针对克拉玛依油田五区八道湾组J1b5储层油水分布复杂、测井资料解释难度较大、测井解释符合率偏低等问题,研究了该区储层的岩性、物性、电性及含油性两两之间的关系;采用岩心刻度测井的方法,建立了该区泥质质量分数计算模型、孔隙度和渗透率解释模型,根据储层特点建立了含水饱和度计算模型,模型经验证均具有较高精度;结合试油层段孔隙度-电阻率交会关系,建立了五区八道湾组储层的解释标准。该方法能有效提高储层测井精细解释的准确度,对储层综合解释及剩余油挖潜研究具有指导意义。Aimed at the characteristics of complex oil and water distribution, difficult logging data interpretation and low accordance rate of logging interpretation in J1b5 reservoir in Karamay Oilfield, this paper carries out research on fine logging interpretation. The lithologies, physical properties, eonductivity and oil-bearing properties and the relationship between them each other of the reservoir rocks are studied, which lay a consolidate foundation for establishing fine interpretation model. Based on the four-property relationship and using core analysis data to calibrate log information, the mud content computation model, porosity interpretation model and permeability model are respectively set up. On the basis of the reservoirs characteristics, water saturation computation model is established. The established model possesses high precision. After thai, combing with the porosity and resistivity intersection relation of the test interval, the interpretation standard of the reservoir is set up. This method is effective to improve the accuracy of fine reservoir log interpretation and has guiding significance for comprehensive reservoir interpretation and remaining oil redevelopment.
