摘　　要：针对南襄盆地泌阳凹陷页岩油风险探井阳页油1 HF井在钻探目的层段过程中存在的地层对比方面争议,通过录井、测井、随钻井下测量资料分析,优选气测iC_(4)/nC_(4)、Mg元素、自然伽马、电阻率等标志性识别参数,以导眼井阳页油1井完井资料为参照,结合钻井轨迹上下切地层资料,对阳页油1 HF井目的层段的各小层层位进行精细识别,确定不同小层界面深度及钻遇最老地层深度,从而消除现有地层对比上存在的争议,并为该区域随钻地质导向及钻后地层精细对比提供指导。Aiming at the controversy of stratigraphic correlation that exists in the process of drilling objective intervals of well Yangyeyou 1 HF,which is a shale oil risk exploration well in the Biyang Sag of Nanxiang Basin,this paper optimizes the symbolic identification parameters such as gas logging iC_4/nC_4,Mg element,natural gamma ray and resistivity through mud logging,well logging and downhole measurement while drilling data analysis.Taking well completion data of the pilot well Yangyeyou 1 as a reference,combined with the up and down cutting formation data of the drilling trajectory,fine identification is carried out on the position for various sublayers of the objective intervals of well Yangyeyou 1 HF,determining the depths of different sublayer interfaces and the oldest formation encountered during drilling,thereby eliminating the existing controversy in stratigraphic correlation and providing guidance for geosteering while drilling and fine stratigraphic correlation after drilling in the area.
