针对松辽盆地北部大庆油田高台子致密油藏，采用地球化学研究结果与测井技术相结合的方法，建立了烃源岩特征参数的测井解释模型。在微观孔隙结构特征研究基础上，应用岩电实验和核磁实验资料，开展了储层有效性评价，为致密油层下限确定探索了一种新方法。以岩石力学理论和实验为基础，建立了脆性指数、地应力等参数解释模型，形成了一套致密油测井评价技术，评价结果应用于研究区储层压裂改造、井位部署和储量综合评价中，见到了良好的效果。

For the tight oil sandstone reservoir in Gaotaizi Formation in northern Songliao Basin, the logging interpretation model for source rock characteristic parameter was set up by geochemical and well logging technology. Based on the microscopic pore structure study on mercury injection data studies, reservoir effectiveness evaluation was carried out by rock-electric experiment and NMR data, which explored a new method to determine the reservoir low limit of the tight oil sandstone formation. On the basis of rock mechanics theory and experiment, parameter interpretation models of brittleness index and earth stress were established. The above methods form a set of logging evaluation techniques for tight sandstone formation. The application of these technical evaluations in fracturing innovation, well plan and reserves comprehensive evaluation shows good results.
