摘　　要：岩心作为地下地质信息的最直观的载体,可以直观地提供储集层岩性、物性、含油性的信息,其在油水层解释中的作用不容忽视。基于岩心资料在大庆油田中浅层油水层解释评价中的应用情况,从岩心资料观察技术入手,重点分析了岩心资料在样品采集、含油显示落实、油水层精细解释等方面的应用方法,并通过岩心资料在大庆油田中浅层J 67井等疑难井解释中的应用实例,证明了岩心在油水层解释中不可替代的作用。统计2015-2017年来大庆油田中浅层试油井64口(其中取心井26口,非取心井38口),结果可知:取心井试油60层,符合52层,符合率为86.7%;非取心井试油68层,符合56层,符合率为82.4%。取心井的符合率明显高于非取心井,表明岩心资料在中浅层油水层解释中所具有的重要作用。The core is the most intuitive carrier of underground geological information,it can intuitively provide the information of lithology,physical property and oiliness of the reservoirs,and its role in the interpretation of the oil and water layers can not be ignored. Based on the application of core data to the interpretation and evaluation of the middle and shallow oil-water layers in Daqing Oilfield,the author focused on the application method of core data in sample acquisition,oil show implementation and fine interpretation of oil and water layers from the observation techniques of core data. The application of core data in the interpretation of the difficult wells such as well J 67 in the middle and shallow layers of Daqing Oilfield has proved that the core is irreplaceable in the interpretation of oil and water layers. Statistics from 2015 to 2017 of 64 wells( 26 cored wells and 38 non-cored wells) from the middle and shallow testing wells in Daqing Oilfield showed that 60 oil tested layers from cored wells were in line with 52 layers,the coincidence rate is 86.7%,68 oil tested layers from non-cored wells were in line with 56 layers,the coincidence rate is 82.4%.
